Thinking of getting a front lip for my car. Its a Greddy style lip and is made of FRP but I remember reading either on here or the other forum that certain materials crack and the paint cracks also but which materials should I go for? normal fibreglass, FRP, or PUF(?), ABS, etc etc???

Greddy kits are made from durable urethane.
Wald kits are made from FRP

so PU is the better option in general then as its more durable but still flexible? As for the greddy kit....the lip I can get hold of is a replica but a high quality replica but is made of FRP....worth it or not? Maybe I could arrange a group buy?

Oem bumpers are made of polyurethane, which I think is the material of choice.

I think FRP and GRP are more susceptible to cracking even in light impacts aren't they?

Yeah the trouble with fibreglass (FRP and GRP) is that if you scrape a kerb accidentally it is a lot more likely to crack than a plastic lip, which will generally just bend.
