kw v3 feeling floaty
so ive had my kw v3 on my car for a bout 1K miles. im running m3 front control arms and m3 front sway. vorshlag camber plates.
my tires are kind of big and in m3 fitment so i did the e9x hub swap. 27540r18 mpss. when i floor it by myself i would barely get any rub. now after about 1K miles i get more rub when riding alone, is it cause the springs have settled? also when i have passengers flooring it i get alot of rub. and while cruzing around corners with passengers it feels way floaty. is this normal or is there something else i need to adjust.? my whole asss end feels like its wiggling when i nail it.

And do you have stock subframe bushings? |

That's likely to be the rear subframe moving around on the flimsy stock bushings. Better to get the rear subframe bushings replaced with something firmer. M3 ones are a good choice, but also some aftermarket options.

Yes I'm still on stock subframe. I actually have an m3 subfram with lsd I will install eventually. Curious to feel the difference.

isn't a 275/40R18 way too big for the rear? Since the overall diameter has changed so much then the traction control system and/or e-diff is no longer effective because the rear hubs are turning slower than the front hubs.

I did a 1m conversion so I can fit larger tires. I also did the 335 hub swap

#2) Bushings: Upper strut mounts and Rear subframe bushings #3) TIRES: How stiff are your springs? I have 16k springs and they cause my winter tires to bounce around like beach balls. 200TW (sporty stiff tires) bounce around too but not as much. 40TW RCOMPS are the only tire iv'e had on the car that seem suitable to be able to handle the higher spring rates. The ride feels BETTER (smoother) with the stiff shoulder rcomps than when rising on 200tw street tires. The winter ties feel as you describe, sickening bounciness. To test #3, try jacking up tire pressures to 45psi. Last edited by bNks334; 11-01-2017 at 12:16 PM.. |
