Default What spring rate

Running QA1 lowering springs on my car(on it when I bought it), fronts are rated at 315 lbs.. I always have a problem with the front end sort of floating if I hit a bump and bottoming out if it's too big a bump(that I missed). Should I be running a higher spring rate up front? Shocks are QA1, 12 ways..
Thanks!

Heh, thats what drag shocks do.
Your car is floaty because your shocks cannot damper your springs (springs naturally want to make your car "bounce", shocks are supposed to control the springs from doing this. Drag shocks on the other hand are all about weight transfer, and have little rebound control, hence the floaty, disconnected feel).
There is a way to fix this, get shocks made for handling.

The OP switched to good shocks, problem solved.

Thanks for the info.. I'll stick with the floaty feel, like the straight line handling myself...lol

Yeah I never drove on those shocks myself but I'm guessing that they allow the front end to travel pretty free for better weight transfer. I can imagine that might be more prone to bottoming out on the front air dam that hangs down.

How firm a setting do you have the front shocks set at ? could be they are at to soft of a setting.

Well I just had them rebuilt and revalved to an "R" series.. The only thing I seem to be able to change now is rebound, compression stays constant at all settings... I thought it(compression) would also change with the rebound, but it doesn't. The higher I set the number the harder it was to pull the shaft out, to the point I couldn't pull it out no matter how hard I tried, compression stayed the same.. I called the place that rebuilt them and was told compression was speed sensitive and I wouldn't feel a diff by hand. I don't know, maybe I got screwed on the rebuild/revalving.. I'll try setting them up a couple notches and see if it makes a difference or not.. Thanks!

Hey Lee,

I upped the fronts by 2, really changed the feel.. I guess because it's not allowing the front to come up as easy as it was before.. I'll just use the low setting for the track.. thanks!
