Hey Maddie, the V-Spec suspension is okay,in fact they are really good on the road. But on the track they feel like jelly!
I changed them to HKS Hiper Damper with HKS springs which was okay but the car understeers like crazy. Dunno why.
So, back it went to the mechanic and a set of Eibach Racing Pro was installed. They run well on the track and on the road they are reasonably comfy though not as compliant as the stock springs or the HKS. If you put the Eibach, watch out for bumpy corners on the road as the car bounces quite a bit and traction is easy to lose. That's okay for me as I seldom speed on the road (that might change if I spot a Modena or Diablo in front or at the rear
).
A friend of mine running a huge TO4R single turbo on his GTR uses a higher rate Eibach with 4 springs at the rear and it is really fantastic on the track. On bumpy roads though the car bounces like a pregnant woman.
