Thanks. You make some good points. The H&R's are progressive (don't know about the stocks). They are stiffer than stock, but I don't know the load rating difference. I'll look into it. I think that putting on both F/R would lower the car even MORE (proportionately) in front (1.4 inches) compared to the rear (1 inch), so it would "look" even worse than it does now. That can't be good for handling either.
Either way, since these are the only springs available, I can always add the fronts later, or switch the rears back to stock if the minor variation in how it handles (if it's even apparent) is somehow worse than having to look at the drc mullet (business in the front, :trash: in the back). I will definitely post pictures whichever I do.
Most understeer-prone track/race cars have stiffer rear spring rates to help compensate, no? I really don't think my car is going to flip over in a corner just because I stiffen the rear springs (I'm willing to take that gamble), or even lose a couple seconds/lap at the local track. I should be so lucky as to have a local track.
