Just Tell Me This...

Order of tuning...



First suspension, then LSD?

Or LSD then suspension?



More specifically, what order do you set your cars up in, even if neither of these examples are specific enough for how you go about starting a tune?



EDIT: I'm talking about cars that you will use a lot competitively online, etc. Not just to win a single race or event in A-Spec. And I'm not talking about adding purchased parts outside of fully tuneable suspension, LSD, aero. Not stage 1, 2, 3 turbo, or weight reductions, etc.





I'd really appreciate the input.

Thank you.

In A-spec, for cars that I think I'll only use for a handful of races, all I will buy is sports softs, full suspension and lsd, then try the event. Nine times out of ten, that's enough for me to win A-spec. Beyond that, I add ECU then air filter, etc. enough to keep the events a challenge, but to level the playing field a bit if the AI are unrealistically fast.

I mean for online racing, as in: This car is going to be my go-to car, I want to do it right - best possible handling, everything. Where do you guys start, based on the original questions?

 

[Motor City Hami]

Build to the level of the restrictions for online. Online racers aren't as dumb as the AI or maybe dumb in a different way. Online can only restrict HP, weight and tires, so add everything else.

Sorry, I don't mean adding parts. That to me isn't really even tuning, it's upgrading. I'm talking about suspension, LSD, brakes, etc.


thanks

 

[Motor City Hami]

??? so are you looking for a tune? I thought you asked what parts to add first?

If you are asking which to tune first, I don't think you can tune one at a time. I have a fairly standard suspension tune and LSD tune that I will put on. Next I will fine tune the LSD. Then I will fine tune the suspension. Then I will fine tune brakes.

Is that more what you meant?

 

[SS_1182]

Yeah, that's closer. So your answer is that you have default settings across the board that you go from, and you start with LSD settings.



I'm wondering if other people actually take the default tunes that come with the cars into consideration. Some cars have lower spring rates in front and higher in back with default settings, others it's the opposite. I wonder if those can be trusted as far as weight distribution goes and overall balance of the car is concerned. But that could almost be a tangent to the original question.

Lol... The simple question is Suspension first.
LSD should be fine tuned after.
You can use LSD to cheat the suspension, but you should use the suspension to base your LSD options.

 

[SS_1182]

Thanks for the input Adrenaline. That's my theory as well, but I'm still curious to hear other tuners' preferences and if they vary.

The defaults are bogus in my opinion other than springs and ride height on high end cars and RMs. Every car in the game ships with the same shock damping number, zero camber, same toe.

I start by looking at the springs and the ratio front to rear. Example if a FR car comes with 8.5 front spring and 8.0 rear spring. I may move both of those up to like 10.0 and 9.0. Then I put the dampers so they sit on either side of the spring rate (compression a little lower than the spring, rebound a little higher than the spring).

Beyond that I have my own default settings for each type of car as my starting point. Just fairly logical settings to start with. Then my own default LSD setting, then hit the track for fine tuning.

My defaults...

Personally, I rough the suspension in, rough the LSD in, fine-tune the suspension, then fine-tune the LSD.

Improper LSD settings can mask suspension issues and (to an extent) vice-versa.

Nope to both.

They always have equal f/r and compression/extension dampers but the numbers change car-to-car. Seems 4 is the lowest on default dampers, 8 is highest. Camber has many exceptions; some cars get 0.5 on one end or the other, some (Z33 Fairlady for example) get 1.0/2.0, some get ridiculously high amounts (4+ on the Amuse S2000 R1), etc etc.

Thanks for the discussion. Already getting some good info here.

Like all tuning, it's an iterative process, but LSD has a bit more potential to mask suspension problems so that's where I start.

You can use LSD to cheat the suspension, but you should use the suspension to base your LSD options.

You can give the LSD a quick tune, or temporary tune, because having the LSD settings too high is going to effect the turn radius of the car, so tune the suspension all you want in frustration and make no progress if you have set values to high, especially for initial and brake.

My process would be more along the lines of:
1. LSD - quick dirty setup
2. Suspension - tune with car on low power and 1-2 tire grades below desired end usage tire grade.
3. LSD - fine tune

I tune similarly.
1. LSD and Suspension - quick setup
2. Fine tune LSD
3. Fine tune suspension
4. Fine tune brakes, if necessary, to improve turn in.

Adrenaline and Rotary Junkie pretty much nailed it, I do the same.
