Just wanted to add to my review above.

Second time out, on a handling track (Wakefield Park), the car felt fantastic! Adjusted the shocks, and it transformed the handling. An alternator problem brought my day to a premature end (only did a total of 9 laps), last lap was fastest, a couple of tenths off a PB on shitty old tyres and no aero (still).

Very happy. Its official, delrin rocks.

:D

This is good to hear. I'm halfway through installing my Delrin kit from these guys in the blue car in my signature. The poly bushings were complete mush, I'm expecting a significant improvement as well.
