Pi springs any good on mk3 rs ??

H&R, tons of threads about this already if you Google

 

Or cooksport

 

Yeah if you you like hard crashy springs

 

Can't say I have ever heard of anyone using Pi springs on one of these. I remember them being all the rage back in the Max Power days, didn't realise they were still about.

H&R is probably a safer choice as it's well-used and fairly well-regarded.

 

Mine must be faulty then because they arent hard or crashy
