GT3 sway bars??

on GT3 bar settings stiffer than position 2, the M030 struts can't properly damp the higher spring constant of the GT3 bar, so porpoising is a problem.

on the race track, i tend to run the GT3 bar full soft and the rear H&R bar full stiff. the handling is RAZOR sharp like this with no understeer at all. i run tire widths of 225 / 265. i think this works great with my setup. you can get REALLY aggressive with the car like this as it's tough to provoke understeer. you can really whip the tail around; it's quite a lot of fun.

i have run several different settings on street & track; for me, the GT3 bar stays full soft at all times. i move leave the H&R full soft for street, full stiff for track.

i did mention that for an S, the H&R bar may be too stiff in back. the added power of the S will cause the inside rear tire to spin under hard acceleration out of corners. this can be corrected with a limited slip differential or by using a softer rear sway bar (M030 base bar is great).

if you take your car to the track or are a real performance enthusiast who doesn't mind sacrificing some comfort, the GT3 bar is a great upgrade. if you favor a reasonable blend of performance with comfort, the M030 setup you mentioned (M030 S front, M030 base rear) is impossible to beat.

Thanks for your input! Please PM me the price on the drop links. Since I have a few extra HP I would really need to et LSD in the back before I do the rear don't you think?

it's not the extra HP of the S, it's the torque. if you have a lot of low end torque, you'll get some wheel slip with a stiff rear sway when exiting slower corners.

Insite's got a VERY stiff suspension set-up and only uses the softest setting on the GT3 bar. Even though the GT3 is a lightened Carrera, it's still 150+ pounds heavier than a Boxster. It looks to me that you'd have more adjustability and still have a very stiff system with H&R front and rear.

the H&R bar is really almost as stiff as the GT3 bar. it's actually got the same number of usable adjustment settings as the GT3 bar. the H&R has three settings. the GT3 bar has five, but you really can only use three on the Box or 996 because the pick up points are different than the GT3. on our cars, the stiffest 2 settings of the GT3 bar cause the sway to actually bend rather than twist. it's hell on the power steering pump and gives some VERY funky steering feedback on the stiffest setting.

Addco also makes a set of bars. There are plenty of options out there, but you don't necessarily need to go with the stiffest you can find. Remember, stiffer bars actually REDUCE grip without changes to anything else and will somewhat effect everyday driveability, so you have to first decide what you're doing with the car before you pick the sway bar set and suspension you want.
