Bilstein suspension built specifically for my last Silvia S15 with track and Targa work in mind using Eibach springs with 6 / 4 spring rates by the suspension engineer at Heasman's Steering in Sydenham. If you don't know they are Australia's main Bilstein agent. These are internally the same as other kits sold to several Time Attack entrants costing over $5,000 and probably very similar to Heasman's own NSW Sprint Series car. Which is here
The only difference is that these are non adjustable. I know enough to know that the experts can set the valving much better than any knob-twiddling that I could do. The rates set by Heasman's work very well for track or Targa type work.
Suspension cost over $3100 alone plus the camber tops @ $300 as listed here
and the invoice is attached here as proof. These have done less than 15,000 Ks and are in as new condition. They have a few marks and scratches as most of those Ks were done on Targa type roads and rural Queensland.
