Yeah, Ive been running it this way for as long as Ive had billet uprights back there, 3 years I think? Plus a bunch of other people that just need more travel.

 

ok. will give that a shot tomorrow night. want to get into about the range i'm looking for before the alignment. really though, no impact on camber? the pushing out motion for camber isn't as "direct" when it's flipped upside down. maybe peanuts. i'll give it a shot and see.

 

i juts snapped a quick pic. so it doesn't make contact with the rear sway bar when u flip the arm? it looks like it'd be very very close.





also, i was deeply confused on my spring rates. i'm NOW at 8/12, and considering going back to 8/11. sometimes it felt like i couldn't get back on the throttle without the car drifting out on me on 8/12. figure maybe with the uprights, added grip etc., particularly in the front, perhaps 11k rear may work better?

 

im at 14/20

don’t go to 11

 

why's that? i did have a lot more confidence getting on the throttle, which is the evo's main strength.

so i juts hcecked, 12k spring in the rear is bout 672lbs, 11k is 617. with the acd & batt relocations to trunk, net, i've moved about 60lbs to the rear. obviously split between right and left, but perhaps that helps bridge the gap between 11k and 12k?

 

probably your swaybar is in full-stiff? i ran 14k/17k no aero (too lazy to switch springs between autox & track) and the rear was loose before I went full soft on the swaybar.

 

not on full stiff.

anyone want to confirm? i dont see how the flipped arm would not touch the sway bar, at least when the car is set down. sway bar is the whiteline heavy duty 26mm

 

the swaybar moves with the control arms/axle

 

:facepalm:

Do you think the relative middle and inner point change with the flip? The shock is still the shock.

About throttle exit, Softer rear springs make a global change, throttle exit is just one aspect. So you give up front grip for the sake of throttle exit when you could just run some rear toe-in. Also, check rear diff preload. I bet its close to zero.

 

i ran 12/18 on stock uprights and then did uprights and didn’t change anything else.

i felt like on high rates in the rear with stock uprights it was super loose when the tires were cold. After doing uprights, even with cold tires the car wasn’t as loose and found myself wanting more rear ended rotation once the tires got up to temp.

I don’t think I’d go softer.

I plan to run stiffer springs all around this year

 

great input, thanks for that. did you do the rear uprights too?

 

I found the rear super loose when cold too the higher the spring rate. on the exit of high speed corners i would get a bounce/hop from the outside rear which would unsettle the car also.

I dont run anywhere near as stiff as most of you guys. not sure why it doesnt work for me. i think im 12/10 currently.

I dont know what the differences are or whether things like running slicks and aero etc would have an effect on the spring rates. Would be interesting to compare and understand whats happening.

Im assuming the majority of you guys running big spring rates are on semi slicks? or are you guys also running big rates on slicks also.
Apart from that i have the larger diameter whiteline rear swaybar but i think a few of you guys also have them?

 

Yes, SSB uprights front and rear. Never had issues with the Ohlins DFV on rear height either

 

my 8/12 setup is on 200tw street tires, factory aero

 

youre probably on fresh asphalt? older asphalt tracks near me have concrete patches. youre not going to get the best grip if you leave that patch
fresh asphalt also have a slick layer of dust. one local dragstrip closed because of dust from a neighboring business
