Who has modmax springs in their motor?
What cams are you running(lift,duration,etc..)?
How many miles do you have on them?
Is your car an auto or manual?
How many rpms are you spinning to before shifts?
Stock or bronze guides?
When did you purchase them?
Have you broken any springs?
If so...intake or exhaust?

The cam specs are in my sig. I broke them a few times, both ex and intake, did'nt matter.
Bottom line, get the comp/crower beehive springs.
BTW, I don't have a problem with modmax, I have bought lots of parts from them (but no more springs) :)

I agree the Modmax springs are suspect when you put power through them. Right before I sold my car, I broke a Mod Max spring. They were less than a year old and were quite noisy. People that have not broken them yet haven't put any boost behind them probably. What an expensive repair to add to the loss I took on the sale. This was also with stock cams. We replaced them with FompK springs and I believe the kid that bought the car broke another valvespring 2-3 days after he picked it up.
