I've not done the mod myself, but I have driven with my buddies pedals who has the original Nixim mod done, and the difference is night and day. Easily one of the best modifications you can do to your G25 or G27 pedals, and it is extremely affordable.

I would suggest you either hard mount, or place the pedals against a wall because there is a lot of resistance, and the carpet grips probably wouldn't hold causing your pedals to slip all over the place.

While im not so keen on these guys game reviews (its all subjective anyway) there pretty spot on IMO on the hardware they review. They have pretty much tried all the pedals out there and there mods. They seem to really like it so that says alot. Price aint bad either.

As far as they're concerned, every blockbuster driving release is a worthy buy, no matter how arcadey, no matter how dumbed down the MP....admittedly, they do warn hardcore sim players not to buy some of these games, but they really should change their name to "Inside car racing", as that would be far more accurate.
 
I've used it for over a year (the older mod) even without hard mounting my pedals and it's worth every penny. It's the next best thing to a load cell with half the cost.

Yeah, this is really strange.
They take in a headset that they get sent and they are always the same basically:
"A little too expensive but if you can afford it buy it".
Gets old a little quick.
BUT, the wheel reviews I feel are pretty nice though, but the other stuff not so great.

Wanna say though, liking ISR more and more.
They make some great episodes like the wheel buyers guide, but I think they have to be a little more specific.

On topic, this seems like a really easy construction, or am I wrong?

Don't think you could make it easier, and if we're to believe ISR, they feel it's just as good as an ARC{based on how much they like it}.
By all accounts, the original nixim mod, V2, the ARC mod, and the perfect pedal are all excellent, with the PP being the odd one out due to costing more than a superior "set" of CSP's.

Being that nixim2 is now better than the first one{heavier more progressive spring}, it almost seems pointless upgrading from nixim to anything other than the PP or CSP's.....but I have a hard time accepting the value of the PP as by all accounts, whatever precision they have, one can acquire it from the CSP and have better clutch and gas pedals to boot:)
 
Just ordered the Nixim v.2 spring set. When they arrive I will do a quick review. For 36 bucks how can you really go wrong? I'm not paying for the PP or the ARC when I could buy a full set of CSP's. To me, I feel that this new Nixim is the best route for G25/27 owners. And I've been looking for a while now.
 
Cool if you don't mind let me know what you think. According to the ISR guy the clutch should be left alone and only the brake spring should be changed.
 
I've orded my nixim v.2 mod already and it's sitting in my desk drawer waiting to be installed. I'm just too lazy to finish off the other required work on my rig to get around to it :(

I'm interested to know though, clutch friction point on gt5 is not adjustable. So does anyone know if installing the clutch spring is a good fit to gt5's in game clutch? Otherwise, i'd just avoid this part of the mod.
 
Hey, bluecat, just curious but how long did it take you to get yours from the time you ordered it? Isn't Nixim based out of the UK?
 
Ok this may sound crazy but i ordered the nixim mod before I even connected my newly arrived G27 on my PS3. It's so cheap I guess I ought to try it anyway, but since people love it I am sure i will too! I checked the brake on the G27 pedal with my hands and it's not as hard as it should be! Gas and clutch are ideal though! I am not sure I will use the clutch mod, it might get too hard after it.
 
nsane, took something like 2 weeks, felt a bit longer. Just as i started wondering why they weren't delivered yet they magically arrived.

After about a week of initial testing, here's my mini-review:

I had to get acquainted with the new pressure, as I usually wear only socks.
The increased tensions are definitely intended for you to wear some light footwear.

Brake pedal - feels real good once you adapt to the throw and pressure. Im using the rubber piece so you dont have that bottoming out feel. Best Mod for the money of course if you dont want to pay an arm & leg for a load sensor based mod. The brake now has the progressive feel a real brake is supposed to have.

Clutch - I started with the included clutch spring and noticed the real increase in pressure required. IMO, it was a bit too progressive and stiff. The clutch almost felt like the brake pedal thats about 15% less stiffer. The Spring shortens the clutch travel distance to about 75% of the original distance - because of that, I noticed by H-T downshifting accuracy increase. It made it hard to miss-shift. However, the actual "feel" of it just didnt feel like a clutch Im used to on a normal car.

My final setup: Clutch - Using the stock G25 Brake Spring - Stiffer than stock, best simulates that smooth throw on a real clutch. Using this spring leaves you with the full throw of the clutch and increased pressure.

Gas - Using the stock G25 Clutch Spring - liking the increased tension. Might remove one coil to lessen the stiffness. I would like to make the stiffness a bit less than the clutch.

Brake - Nixim Spring w/ Rubber.
 
Looks like Nixim orders might be delayed. I got on they're website today and found out they have been slammed with orders since the ISR episode came out. I don't mind waiting for a quality product though and I'm very glad they informed us instead of just having us wait in the dark like most manufacturers... ahem, Sony, ahem, Polyphony.
 
Hi Bro Nizm069
I should have read your post first.. haha before assembling the NIXIM mod. I was lucky and i ordered before the ISR episode and Dave is a very good seller..Constantly communicating with me over emails on status whenever I asked and I got the item ship to Singapore in less than 2 weeks with no hiccups. You mention it is easier not to mis shift but i experience the opposite...it is harder to shift down to correct gear now when I do heal toe braking... maybe should use original brake spring for the clutch like you said...

My mini review:
I am using G27 and recently installed NIXIM mod...the brake is now indeed better and more realistic.. as it is firmer and you need not push all the way in...to get full braking.. But then u have to adjust to the new distant because when you press half way it is full braking lock already... Nonetheless i feel it is better than original..More precision.

but for the clutch it is pretty stiff and now i can't heel toe and shift accurately.. still practising...On the other hand, I had always felt the original clutch spring too light as compared to real cars..

I just had an interesting thought. I read on the forums somewhere that the g25/27 pedals need to be depressed fully once when you start playing GT5 for the full travel to be recognised by the game, and its something that i seem to have noticed too since reading it.

Does the decreased brake pedal throw have any noticeable effects in regards to this? I would assume the game would just use maximum of the smaller travel distance as 100%, but wouldn't that also mean less 'resolution' in the brake input? (if that makes sense)

I would hate to think that with, half the original throw it would mean half the braking resolution. But that doesn't seem to be the case judging by the satisfied reviews in this thread.

Potentiometers are analog just as a volume knob while resolution is like "digital markers" place along the distance of the potentiometers. So if the pedals has 256 resolution then there will be 256 markers along the full distance. This is what it means you need to calibrate you pedals (wheel does the same automatically) every time you load up GT5. Notice you have to press the pedal so far before it registers to have enough "space" to place all the "markers" . The farthest distance travel will register 100%. the more the throw the more these "markers" will be spread out.

It's the same with the steering wheel. For example Fanatec wheel has the resolution of 65535 to the right and -65535 to the left. No matter what degree of rotation you use (270-900 degree) all 65535 digits in both directions will be used.

Now the old Nixim mod did shorten the brake throw some but no where near what the load cell mod does. The new version is supposed allow the full range of pedal throw as it uses a shorter piece of rubber along with the new brake spring.
 
Hi guys
just a quick comment here -

I'm not sure if you have the facility in your game settings but you should dial in around 35% deadzone before the brakes begin to effect the car.

This is intentional as all car brake pedals have a small amount of free initial movement as the brake pads clamp onto the brake discs.

When you install the mod you will "feel" the pedal tighten at this point so you are better able to delicately feather the brakes.

Once you have the deadzone set, then move onto the sensitivity to adjust the foot pressure to your preference.

hope this helps.

Dave
 
How can you change the dead zone? I dont think you can do that in PS3

Hmm! - thats what I thought, and thats why Boons said - "when you press half way it is full braking lock already", because in GT5 you cannot tailor the game software to exactly match the profile of the mod as you can on PC so it feels a little "odd", although this second version of the mod is a much better profile for GT5 than the first one.

It may take a few laps to adapt to the new mod but overall it will feel and perform better than the original.

Dave
 
Just make sure when you first load up GT5 (after your wheel calibrates) you press the brake pedal as far as it will go to calibrate the full throw. If you only press the brake pedal half way then the half way mark will be where the 100% braking will be.
 
Wow Dave tks for posting here n sending my item so fast. Maybe when every game start I never press brake pedal full down to calibrate. Will try again. Cheers!

Lol, you were one of the lucky early buyers, we have sold out right now and hundreds have ordered and are sat there waiting for fresh supplies to arrive this week. So I guess some here will be waiting too.

This thing about fully pressing the pedals etc when you boot the game, it is something that has to be done on PC too. i.e full press the pedals and fully turn the wheel both ways. Do it with all games to be safe. And yes you can press the brake fully through its stroke.

Dave
 
I've been using the original NIXIM brake mod for the last few months and yesterday received the latest version. I got it installed no problem and it works well. Tried it on both iRacing and GT5. The clutch spring feels a little stiff but it may well be I just need a little time to get used to it. As for the brake spring and rubber - it feels great, even better than the original mod. In GT5 I found it much easier to modulate the brake, under heavy braking, adjusting as necessary in the braking zone.
