Sonny was able to manage Blub to a new overall N/A 86 and also Mod class lap record for Buttonwillow 13CW, 1:58.901
I say manage because we did this on stock shocks. The valving on them works for low grip tires and more neutral setup. On higher grip tires and a bit more free setup, it was not happy over the lumpy, kerb laden Buttonwillow. Rear end constantly trying to step out. We didn't have time to test before round 1 so we took our best guess based on the previous setup. That was a 20mm Whiteline front bar, stock rear and front roll center adjuster kit. We were close, but not quite enough front bar. The key is the heavy low speed damping of the stock shocks and virtually no digression. This means they're actually too stiff even for the RCE springs, making the car too sensitive to pitch changes from pedal inputs. Yet the shocks don't adequately blow off on the kerbs so they upset the car way to much. Worst of both worlds. Very much a knife edge to drive at the limit. The car actually would have been better with softer shock valving overall.
This all gives us a lot of useful information in where to position the damping sweep and curve shapes for our Xidas. We'll definitely be able to improve the ride quality with spring rates 2-3x higher than stock and also get it to soak up the kerb hits without upsetting the car. We are really eager to get the first set of protos on Blub!
