It's larger than the M030 front bar. TRG makes a kit that looks close to the H&R.

Eibach makes a kit as well that looks like it's close to the M030 in stiffness.

eibach's front bar is almost identical to the S M030 in stiffness. compared to the PRICE, however, an M030 bar from sunset is less than half the cost of an Eibach.

a note about H&R's customer service: my rear bar destroyed a bushing in less than 2 months because of a defect in the bar; the metal stops that keep the bar from sliding back and forth were too close together. i fixed the problem easily by tapping the metal stops outward, but H&R charged me for a new bushing: $50!!!!

IMO, this should have been free and handled by H&R. instead, they refered me to AWE Tuning, who charged me $35 for the bushing and $15 for GROUND shipping.

I know I've mentioned this before, but both the H&R and Eibach bars are SOLID! They are both WAY stiffer than the GT3 bar. And in my opinion, way too stiff for a Boxster.

The GT3 and M030 bars are just like stock - hollow - but stiffer.

the Eibach is actually a 24mm hollow bar. i called them before i decided on the GT3 bar to get a wall thickness; i calculated it to be roughly the same effective stiffness of the M030 'S' bar.

the H&R's are indeed solid. the rear is about 25% stiffer than the M030 'Base' bar on its softest setting. the H&R front is torsionally stiffer than the GT3 bar on its softest setting, but it has a longer lever arm. it is therefore just a TAD stiffer than the GT3 bar on full soft.

the GT3 front bar on the box is a bit stiff for the road, but GREAT for performance. the H&R rear is actually tolerable on the road at full soft. it's a bit aggressive at full stiff.

for giggles, i set the GT3 bar and H&R rear to full stiff for a day. WOW. WAY too stiff for town (and anything other than an oval track for that matter).

Well damn, then Eibach lied to me! They told me that it was a solid bar.

What did they tell you the wall thickness was?

if i remember right, it's 3.8mm, which is identical to the M030 S bar. when i upgraded to the GT3 bar, i already had an M030 S. i was looking for something a bit stiffer, so i compared the H&R, Eibach and GT3 bars. i remember the Eibach front being identical in stiffness to the M030 S, but being about twice as expensive.

Addco, like I mentioned above. Just get the m030. Porsche knows what they're doing.
