Crow and nizpro have a great rep.

I've heard a fair few horror stories about the nizpro ones going soft. Have they changed their design or materials lately?

The set I have in my g6et have been through dyno hell and back, actually outlasted two bottom ends in the car.

In the first motor they coped with 25psi all day every day, ALOT of dyno runs and plenty of R&D 30-35psi hits on the freeway.

I don't really recommend them for too much over 25psi, 550kw, Atomic have great springs for 30plus psi, 600plus

But in saying that at that 600plus level it's best to leave valve train parts to your engine builder.

the perfect valve spring for the majority of xr6 f6 and G6s out there.

haha went to pick up my springs today from sydney from rapid systems ,what a joke !! they had 2 days to drop them of a c motor sports ,rang because I was running late only to find out he hasn't even dropped them of yet ,2 days to drop them of 30 kms away.then ended up driving an extra 40 kms to get them from his house.so 2 hours sitting around in the car ,3 whinging kids ,1 wife abusing me for his stuff around ,30 degress heat and he finally shows up.$60 in fuel ,2 tolls and I get them.then ring my mechanic only to find out im to late to drop the car of to get them done as he was shut..all up a disaster of a day..

wont be buying ANY of there products again.

could have got crow with the extra fuel money and toll money.

yep im having a good old whinge to get it outta my system..

Yeah, from that Henz guy.

Not the first thread I've seen about their delivery times either.

I would have thought for 300rwkw standard springs would suffice.

I was running BF springs cold side and BA springs hot side at 325rwkw and never had any problems.
