Never heard of them but what front clip is it and might could offer suggestions.
Metric clip
Is it Metric with Metric lowers or Nova? The common mistake with Metric lowers is, everyone wants to use light springs like a Chevelle. Heres some basic info to help you.
Chevelle lowers have a 36% ratio
Nova Lowers have a 30% ratio
Metric lowers have a 23% ratio
Meaning that if you use a 650# spring on a Chevelle lower 650 x 36% = 234# at the ball joint.
To get the same with a Metric lower you need to use a 1000# spring 1000 x 23% = 230.
Metrics also don't have near the travel ability, so if you try to use a softer spring, they bottom out quicker and will push like a dump truck.
From my experience with my metric, I would start with a 1050 in the RF and 950-1000 in LF. 2" off sets on all except RR. Use a 3" or 4" on the RR.
As for rear springs, start with 175# across the back with 30-40# of LR bite.
ok cool thanks alot, just trying to get started out, new to dirt racing, thanks alot
