I just recently bought the neuspeed super cup kit with the race springs from heeltoeauto.com....now the rear shocks have three perch settings and the front shocks only had to. These are the koni yellow shocks with the race springs. I set the perch setting to the last one all the way around i love the look but i have a vibration and shaking feeling now when i accelerate but when i coast it doesnt do it.

does anyone know exactly whats causing this or know what to do to fix it?

How low? On acceleration, axles don't like severe angles.

im guessing prolly close to 3" front and 2.5" rear

maybe thats why

tunerpat05

so do you think i should put the perch settings back to where they were when they arrived and go from there? just the front?

Have you gotten an alignment since install?

Getting an alignment might help.

The vibration is the axles. You're probably pretty low on the low perches. I have mine on the lows in the front and the middles in the back, and that's on sport springs.

Replace your axles with oem or raxles if you're auto, they don't do 6mt axles right now. But get the alignment right away. That may help the vibration, but only slightly. The issue is def the axles and their new angle.

How did you buy a Super Cup kit? I thought they stopped making them years ago.

I was thinking about getting the same kit over a set of coilovers. Do you happen to have pictures of the whole car?

Both Heeltoe and XLR8 sell the Supercup Kit. It's just a package deal for Koni Yellows and Neuspeed springs together, neither of which have been discontinued.

Any advantages or disadvantages with these over ISC or Tein coils?

The Koni Yellows + Nuespeed Sport springs will be very close to stock ride quality...firm but smooth. However, you lack the ability to lower the car more than about 1.75". The ISC's have a large range of damping adjustment....32-way if I remember correctly. The ISC's will also go lower than the Teins.

Thank you, they seem perfect for what I want. I have an 06 6mt and I'm fairly happy with the ride but would like it to feel a little "tighter", I'm sure even new OEM parts would be fine (currently have 125km on them) but a slight drop would nice. Don't have the quality of roads around here to support a nice "tuck" unfortunately.
