Like the title says im looking to put together a good street/strip set up. The car is a bolt on m6. I do some street racing and go to the strip on the weekends. Looking at doing qa1 type r in the front not sure on what spring rate to get and I probably won't swap to coil overs on the back and not sure what shocks to get and what size springs to get there either. Any help or suggestions would be helpful thanks

I do the same thing as you, mostly fast street driving and some racing here and there. Went with Koni 4/4's, Strano Springs and swaybars. Made a hell of a difference..

A 300lb springs will probably work the best for you but it really depends on the front end weight of the car. Have you done anything to lighten the car like get tid of the A/C or add a tubular k-member and a-arms? Have you done anything to add weight like a turbo kit, supercharger, or an iron block motor?

The Strange or Afco shocks will be a better value for your money spent. I have all the correct spring rates for you and plenty of options on the rear setup as well. Give me a call and I will set you setup with the right parts at the best deal.

How do I find out how heavy the front of my car is? I've gotten rid of the ac that's about it for now.

If that is all you have done than I would just stick with the 300lb springs with the QA1s you want to use, it will do everything you want/need it to.. You would need to be considerably lighter to use a 275lb springs and considerably heavier to use a 325lb spring.

And be careful with the QA1 R's. The lower settings are still pretty firm on compression. If you're not getting air under the front tires, you're probably better off to use the standard single adjustables.
