Mid-Entry Level Suspension Setup
 
So guys I have narrowed down a possible Mid-Entry level setup for spirited driving/track/DD use.

B8 shocks
Tarmac Springs (RCE)
Whiteline Camber bolt 16mm
Grimm Speed Strut tower Brace

Now I need to know IF there is anything else that I srsly need to have to permit all of these little mods to work well together.

I have a TOYOTA GT86 (I think it's like the frs, more tail happy then BRZ).
What I'm Searching is to reduce oversteer and have a car that behave in a more neutral way.I just think that the frs/gt86 is to much tail happy especially around here with crap road surface and not very sticky tires.

I like it. That with a good alignment and the right tires would be a great set-up.

So no need of upgrade bushing and sway bar? Do you think that this setup will make the GT less tail happy and more like a brz (neutral handling?) or I will need a stiffer front swaybar?

I want the simplest setup to start learning this car on spirited driving/track without worrying to much about different settings.

I planned this setup with the idea of reducing oversteer and increasing handling/grip

tyres will be 215/45/17 PSS on Enkei RPF1 17x7.5

Honestly I don't think you need the rear LCA. I have Ohlins RT on my car, and with the minimal rear drop I have zero need for a LCA at this time.

what camber do you have in the rear and what is your drop?
toe 0 everywhere? -2 camber around?
@Racecomp Engineering @CSG David @CSG Mike

Is it possible to have 0 toe like factory spec (I think...) without LCA using the Tarmac + B8? I know you didn't test the b8 but probably your knowledge can help you making good guess about it.

mav1178 02-14-2014 04:22 PM
I'm around -2.25 front and -1.5 rear, toe is virtually zero.

Car is lowered around 25mm front and 20mm rear.

That's quite good. Higher camber in front, less camber rear and toe 0.
I would say is quite good. Will try without LCA then, I can always buy them if needed.

I do like the effects certain bushings make, but to keep it simple you don't need them. They're just a little bonus.

What spring rates are the RCE Springs?

285 for the TARMACS and 250 for the Yellows.

Keep in mind that the Bilsteins historically have run a LOT of gas pressure in their shocks and Koni does not. Most refer to that gas pressure as "platform" which equates to a very flat car in corners. Add in a decent spring rate (250-285) and you have something that feels more like a 340lb spring ......in the corners. I dont say that knocking the Koni's as they are adjustable. I say it so people have a better idea about the role gas pressure plays in the performance.

A responsive monotube, non adjustable damper with a solid amount of spring rate is a budget minded autocrossers nitrogen filled dream !

Koni yellows are twin tubes and the Bilstein B8s are monotubes. Of course there's a huge difference in gas pressure.
