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.

 

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.
