I am looking at getting a new set of shocks for my 06 Spec C, I have already upped the power to 420/400 & have put AP 6 pots on the car. I have fitted Whiteline ARBs & ALK which has improved things slightly. However when on track I believe the suspension is now holding the car back from lapping a lot quicker (along with a spare set of wheels with grippy rubber )

I am looking at the AST kit that Litchfields offer, I am also looking at the Buddy Club Racing Spec Dampers. My car is used daily, so I am looking for suspenion that can be adjusted for road use, but also adjusted to suit the track.

The main difference I am pondering about is that the Buddy Club kit has upper mount adjutable camber control? I am thinking of fitting these with a set of D2 racing adjustable camber control arms.

There are 2 things that I am wandering

1. Will the difference of being able to adjust camber for the track make a big difference on track? (Lap times)

2. Are cars with aftermarket upper mounts a pig to drive on the road? (I here people moaning about knocking noises?)

I know that Litchfields have been using the AST kit for a long time with good results, but will the Buddy Club with camber control have a distinct advantage on track???

If anyone has experience on this subject I would appreciate your thoughts

Bring back that toe adjustment when lowering and making camber adjustments saves wear and tyre over heating issues.

 

Can i ask where you are getting those bits, interested myself

 

If it was my car I would fit the AST coilovers. They worked well on the Type 25.
I have EXE-TC fast road and track coilovers fitted to mine and they work very well.
Any solid top mount will increase NVH.

Hi fella, what is "NVH"?

I am tempted with the AST's because they are a known product, but whilst doing trackdays you see race cars and virtually all of them have a lot of camber adjustment, I am just wandering how much of an advantage it is? I am assuming I could probably get top mounts to fit on the ASTs?

 

NVH = Noise, Vibration, Harshness.
Yes I believe you can get AST's with adjustable top mounts.
I am still running the standard STI top mounts on my EXE-TC's.
I think in order to be happy with your choice you need to be 100% honest with yourself as to the cars use.
If its just a track toy then fill your boots and get rose jointed everything with solid top mounts but if its mainly road use with some track days I would focus on a 'fast road' set up such as the AST's and accept the compromise on track.

 

Nice one fella
