I want to follow Nigels advice and go for the 22mm rear arb. If I can't find one, will a 23mm one be alright? Not really looking forward to making a track car out of this. I will take it to my local track, but it won't be something I will do on a regular basis.
ID-Workz messaged me yesterday (after ordering last saturday) informing that theres upto a 4wk lead time from UR > ID-Workz. for me not a deal breaker, as ive ordered in plenty of time. but be prepared for a wait if you want it quickly
