Corvette Z06 (C2) Race Car '63 - No Tune - Discuss...

[budious]

Anyone else have this car in your garage?

Stock equipped with Race Hards, 628HP, 1168KG...

I was attempting to tune under the following conditions, transmission at 271mph, aero set to minimum of 20/40, LSD default at 10/40/20.

My first instinct was to put it on Sport Softs as I do about everything and tune a spec for it, I tried every trick I know to get maximum grip to the back wheels... no go...

So I equip the stock Race Hards, on the stock suspension setup, it's way too stiff, so I do my usual pre-tune neutralization and drop the dampers all to 4 and the anti-roll bars to 2. Race Hards still spin like crazy, drop the springs some more, no help there either, not to help matters either the bottom limit of the spring rate range is still too high, 4.2F and 3.5R is as low as it goes... I'm thinking it really needs to be something along the lines of 2.1F and 1.7R in actuality.

I did try a maximum weight shift +15F/-35R and -35F/-35R when I attempted tuning it to Sport Soft with no success, will try the same with Race Hard... but I'm thinking this is the first car where I really feel the need to just jump straight onto Race Medium or Race Soft tires I've come across.

On the neutralized pre-tune setup, driving Race Hards down the straight after having spun them a little bit in the corner, they just stay light pink and don't fade back towards white cause of all the torque being put on them... I'm thinking the car has more like 1200HP under the hood...

Just wondering if anyone attempted to tune this yet or had a sweet spot in your hearts for it... I love the challenge, think it's my new favorite red headed step child.

Edit: Since someone else revived the other thread for this car about the same time I started this one, I posted a raw tune for them to try there - reposted here.

Played with it some more, bipolar car... seems a bit more stable at higher than default shock but I'm pretty sure if I could get under the minimum allowed spring rates it would like those also, feels too stiff all around, the extra spring rate boost just helps to make it so rigid it becomes a stable drift car. Just something I was toying with but you can try the raw spec below:

+ Chassis Reinforcement (may be a little too rigid, optional)
+ Aero @ 50/70 for Racing, 20/40 for Formula Drift (seasonal drift trial car possibly)
+ Transmission @ 273 MPH (max, for lengthy predictable gears without sudden shifts)
+ LSD @ 30/60/30 (seems to help a fair bit at these extremes, still touchy on corner, and oversteer and floor it for Formula Drift)
+ Ride Height 0 F / 0 R
+ Springs 10.6 F / 8.5 R
+ Rebound 5 F / 5 R
+ Bound 5 F / 5 R
+ Anti-Roll Bar 3 F / 3 R
+ Camber 0.0 F / 0.0 R (or you can try the default)
+ Toe 0.00 F / 0.00R

Bought this car in the UCD last week.
This is an RM car and it goes like stink.
It came race modded and with a stage 1 turbo,not sure why.
I have added everything to the car and I took it to Daytona and beat the Nascar boy's with it so it goes.
I also did Nur and did a 6:42 with it with most aids on.
It would make a great drift car you are correct.
As a drift car this thing would be great,I'm not a drift guy myself but with all aids off it is great for drifting.Raced it for fun at Daytona and beat the Nascars.I will find my Nur setup and post it.

Ive been looking for this car forever budious. When I do, I will be sure to try and tame this beast. It has been a handful ever since it was introduced to the GT series. Until then, good luck.

Yeah... I'm not entirely convinced it's setup right, or maybe it worked better with the imported settings on the car from GT4 under the GT4 physics engine; physics engine changed slightly but car was un-updated in transition, maybe a partial explanation... it's wild, I give it that, but even on Race Soft I can't say it has the kind of the stability that one would expect from a race car.

Why is it so damned hard to find in the UCD?!

Random rarity of cars to some degree I suppose, I've been obsessively checking UCD for weeks trying to find the Lotus Motorsport Elise with no luck yet.

 

[AirKnight76]

Just got the 1998 Lotus Elise Sport 190 on the UCD for $48k, is that the one you're looking for?

 

[budious]

No, the Motorsport is like a full race car conversion of an Elise. Adjustable front and rear aero, fully upgraded.

[AirKnight76]

Ahh okay, don't think I've seen that one yet, will have to keep my eyes out for that one.

I just bought the motorsport Elise yesterday. It was a nice red color however I can't recall what I paid for it. To me it seems like the more I drive my other lotus cars the more they drop into the ucd... Just a theory.

 

[budious]

Yeah, funny about mentioning things you can't find cause they turn up as soon as you do... it showed up in my UCD tonight after looking for almost a month. Cost about 100k credit, wasn't full raced equipped like I assumed; it's just basically a weight reduced, race body shell with adjustable rear aero body upgrade, a sports kit suspension, and race hard tires standard. You still have to go upgrade it which is fine by me cause I rather fine tune the drivetrain parts selection and perhaps not go overboard on the engine.

Good theory also, I was grinding my 111R Elise last night for cash then it showed up today.

It just looks to me like you really dont know how to tune in this game. spring rates are way too low stock and if you drop the ride height like a normal person they should be at like 10 each and ARB up to 5 or so

 

[budious]

Trust me... I tune plenty of cars, this one is just different, unless you own it and want to share your tune for it that drives plenty smooth; cause I highly doubt you do. A lot of these old model cars stock suspensions are in the 2.2 - 1.8 kgf/mm range. I still haven't come to the conclusion if PD has accounted for the varying designs of linkage and spring ratios in their suspension modeling or is using a universal system. If they do, then this car for stock ride height should have had spring rates that are below the minimums available on the fully customizable kit attached to this car.

 

[Poppins]

yeah but the older cars have massive spring travel compared to the newer ones so you have to tighten the hell out of it to make it handle near good

and yeah i do have the car and i have tuned it with tight suspension and it drives amazingly, it is also modded all the way and has racing softs but more HP and i have no trouble with oversteer and losing the back end, hell if anything the car doesnt have enough torque and should lose the back end a lot more easy then it does, it barely starts drifing if i full throttle it around corners.

 

[Poppins]

all of the old model cars i have are at like 5 kg/mm btw

if you think about that it being at 5kg/mm and having 375+ kg on one wheel that makes it go down like 70 mm which is nearly 3 inches, and that is just sitting and not moving, imagine how much it goes down when you slam the brakes at 150 mph.

same goes with anti roll bars. they need to be tightened

 

[budious]

The tune I posted at the bottom as edited to the original post was much more manageable than my original attempts, I just prefer to go soft over stiff when I can. I like the active suspension, the car is in a raceable state on race soft; but I'd prefer to tune it soft and run sport soft or race hards if I could.

 

[Poppins]

yeah but having it that soft is unrealistic and is just completely wrong, it NEEDS to be in the 10's and arb at 4 or 5 unless you want the car to handle like it has stock suspension and is rolly as hell
