I can report back that the chassis really is working well. Since adding this to my DEX210 the car has simply improved by a good half a lap, it is definately alot more confident under power and just seems to carry speed out the corner better.
Last night I TQ'd Maritime infront of Ben Woods (also using the CRC chassis) by 5 seconds. The car just felt so dialled. The track is a mix of Carpet, Astro, painted wood and wood flooring. I am looking forward now to run this at the next BRCA Regional at Barham in a few weeks time.
Excellent !
