F13 with 918's
F13 with 918's Think I should shim the 918's a touch to run with the F13? The springs are brand new. The F13 has .595/.585 lift. The limiter will probably be set at 6700-6800.
i ran 918s for about 9k with my cam that has .595/.598 cam.. you just need to be really easy on them until their warm. i actually had 2 cracked springs, so from now on ill spend the extra cash and run patriot golds.

You can run 918's all day on those lifts. However I recommend titanium retainers along.
Also, ALWAYS let the car warm up with aftermarket springs regardless single or dual. The material they are made of is simply brittle before they are heated.
