I hate to say it, that is still a momentum car that can out handle most. S50B32 transplants have ruled ST4 around the Utah NASA region until a pesky turbo Miata got dialed in.

I still have a ST2/3 S54 E36 M3. The Boxster really opened my eyes and improved my driving significantly. Really every car should be driven as a momentum car.

Sorry for the thread diversion, I remembered your user name from Bimmerforums.

I took your advice and bought both F/R and installed. Open track day today - car was more balanced and in fact I had to relearn my turn-in as it seemed more tail happy now.

jmitro - Thanks for the update! Did you need any new end links and parts when installing the H&R front and rear sway bars? How does the car behave at street speeds and driving conditions?

[jmitro]

I did purchase new Tarrett sway bar end links, but they aren’t required as the stock end links work also. The sway bars come with new bushings.

At street speeds there is no difference. The car behaves and drives just like usual. And I have not heard any noise from them as alluded to earlier.

I agree with steved0x - the challenge now is to tame the oversteer

[bcrdukes]

Thank you!

At what speeds are you encountering oversteer?

[jmitro]

highest I saw on my dashboard yesterday was 107mph before braking. but oversteer can happen at lower speeds like a 40mph auto-x. just depends on how much one is pushing the car to the limit

Play around and see what you like.

Similar to running an E36 with no rear bar and a square setup.

This seems backwards to me. A stiff front sway bar should increase understeer, removing the rear bar will make this even worse. I run a square setup and have have a GT3 front bar. I couldn’t dial out the understeer until I installed an adjustable rear bar.

I believe that he installed 'both' the front and rear sway bars and the rear H&R's are adjustable :-)
