I know this question has been asked several times by other folks and I'll probably get yelled at for asking. Sorry!

I have recently installed a new set of tires, Yokohama AVS Sports. The fronts are running 275s and the rears with 315s. To fit the rear tires I also threw in a set of 17x11 SS wheels. My question is about lowering. I plan to us a set of Hotckis springs that I have sitting in my garage. What do I need to do get the most efficient and concise handling that I want from the car as a result of lowering, and without the tires rubbing against anything?

Can somebody guide me, or point me to where I could find detailed solutions on how to go about this? Cost is not an issue here, so I dont mind purchasing LCA brackets, panhard rods, etc. I just want the car to handle well, not like some crazy bouncing import, plus I live near some fun switchback roads. Thanks for your help folks!

Feeling the need to carve,
Bob

don't worry - no one gets "yelled at" for asking questions.

The only thing I've seen that's a for sure with the 315s is a slight trimming in the rear inner wheel well.

You may want to check at Install University they have lots of good stuff on our cars there.

Hope that helps.

Best to talk with someone that knows, but I believe you'll definitely need an adjustable panhard bar, to recenter the rear, control arms would be a good idea, and control arm relocate brackets.

I'm partial to BMR, but only because I've had great experiences dealing with Brett and am very pleased with his products.

Well, officially, my car isn't lowered....but it has the Bilstein suspension. When I installed my 17"X11" wheels with the Yokohama AVS Sports (315/35/17) in the rear I got rubbing of the inner tire wall with the inner fender. I bought an adjustable pan hard bar and got everything centered. Next I took the wheels off and "massaged" the inner fenders where the tires were rubbing and then re-undercoated those spots (the tires had rubbed off the undercoating). A friend of mine did the exact same thing when he lowered his car and mounted some Fikse 17"X11" wheels in the back (with the same Yokohama tires that you and I are using). Neither one of us have a rubbing problem anymore.
