Stock Height Performance Suspension?

I'm looking to replace the OEM shocks/coils because they're shot. I want a similar ride height to stock but something with better handling. According to the threads I've researched, it looks like -.7/-1.0" is about as close as you can get with aftermarket springs. Any suggestions? 2001 IS300.

2001 springs are shorter that the 2002 and later from the factory. If you do Eibach pro spring kit will drop .5 inches. Shocks depends on how good you want .

If you want to stay stock height, maybe look into OEM springs. You should see an increase in performance simply by replacing shot coils. You can also add a set of performance sway bars to increase performance without changing height at all. Problem is with OEM equipment is you might wind up paying more for those. I have read that the Eibach Pro-kit springs are about as similar to OEM as you can get with an aftermarket spring, but you will get a drop, and an increase in performance, and it might be cheaper than buying OEM springs. For comparable struts, you can get KYB's. Tokico, Koni's, Bilsteins, etc would be an improvement over stock shocks.

OK, Eibach Pro's it'll be. Should I go with Koni STR.T or KYB's? I've never purchased either brand.

Thanks, KR

The Koni are nicer in my opinion.

Fortune built me some 510s with longer bodies so I could get them to stock height. They didn't even charge extra. I just emailed them before I ordered and told them what I wanted.

You could always go with Bilsteins, and then go with 225/45R17 tires when its time. Aftermarket sways help too

If you want to get better performance, drop about 1", stay in factory alignment specs, go with Tokico Blue and Eibach Pro Kit.
