Cheers! These are the fully adjustable spax. Seem to be really good so far. Wanted to have as much options as possible. Still have plenty to fiddle and tune. Set pretty low with high damping at the moment.
What setup do you have for brakes and tyres? The 16in rins limit tyre choice but allow for the ap racings but the 15s have loads of tyre choice so is there a way to upgrade the brakes on the 15in rims?
We use 16" Abingdon (ex-cup car) wheels which are the lightest option you can get other than the "ultralights" which are very rare and expensive. We use the standard AP 4 pot calipers front and rear with a bias valve controlling the rear. You can't normally fit 4 pots behind Abingdons without a large spacer but we've done some quite serious hub/hub flange modifications so that we are running minimal spacer without affecting geometry to much. Cup cars had special low profile AP calipers. Fitting 4 pots under 15'' wheels requires serious caliper modification which I would say is bordering on dangerous. We use 225/45r16 Nankang AR1's square, which are taller diameter than standard but much wider. There are lots of options in this size as well as 215/45 and 205/45 I think. 225/45r16 is essentially the same tire size as the slicks the cup cars used. In theory you do loose a little acceleration but the increase in grip far outweighs that.
We considered doing that but we actually laser cut and folded 3mm steel brackets that fix to the original fixing locations, which then have 5mm Aluminium seat brackets bolted to them. Probably not the lightest option, but don't think I had easy access to a welder when we made those. I'm 6'2" and fit plenty low as it is now with the boxes still in.
nice
Nice. Are you using the fixed height Spax dampers or the adjustable platform ones? I’ve got a set of adjustable spax’s to fit to mine.

Did you remove the box chassis part underneath the seat and welded new seat rails to have a lower seating position?
