Over-steer or Under-steer... that's the question...

.....just to jump in

After a long time on stock S roll bars am contemplating a change. I feel that the car does not turn in sharply enough and lacks front end feel in turns. There is very little oversteer unless it is wet or I have cold tires.

I am on: 18s along with Michelin PSS (for the street); PSS9s; all three strut braces; adjustable rear toe bars. Tire pressure is 30 to 31 up front.

I was considering a change to: both M030 bars and urathane bushes; camber plates to get the top of the front struts solid.

Are there other specific bushings I can target to get some better driver feedback?

The hydraulic power steering only sends a limited amount of feedback through the steering so a Boxster will never feel like a go-kart or an air-cooled 911 in terms of steering feedback.

But reducing/tightening up any of the slop in the front suspension will certainly help. But I worry that it may not completely solve your issue.

A Boxster Spec car (with 255's in front and adj GT-3 sway front/adj sway rear) has huge front end bite into corners and provides ample mid-corner feedback so you might want to head in this direction by increasing front tire width, stiffen the front sway bar, and soften rear sway bar.

Find someone who will let you drive their Spec Boxster to get an idea of what it feels like. And yes, I'll offer a drive in my car if you want to come to Cali.

Thanks, Tom I will definitely take you up on that! I may be out there looking for work soon!

Would just the GT3 bar upfront while leave the stock S in the rear provide a reasonable balance and starting point? I know many do it and it is all a matter of personal taste but I don't want to get into too much under steer......perhaps it wont be an issue as I am not on the limit at the track. I am just after some bite..

I am on 225s up front (265s rear) and it may be a while before I am able to source the right sport classic II wheel to handle the 255 tire. I think this may be 911 size somewhere in 993 996 18" offerings.
