I have no experience with H&R lowering springs but I'm really happy with my heights on PSS10's, any lower and it will quickly become an issue for me.
I have Eibach sways, Tarret droplinks, LCA Solid bushings and monoball bearings. Car is now really dialed in and more compliant than the ROW suspension that came out.

 

Thanks for the response Jim! Would you happen to know what your measurements are from center of wheel to top of the outer fender edge front and rear?

Thanks, Mike

 

You're welcome Mike. Its a bit difficult to measure to the center of the wheel but I gave it my best shot.

Rear 335mm
Front 326mm

This is within Bilsteins recommended height range adjustment.

 

Thanks Again! I was reading back through this thread and someone posted that there was a different part number for outside the u.s. I see your in Austrailia, what part number was your kit and do you know the difference between the two? Sorry for all the question's and thanks again!

Sincerely, Mike

 

I have the Euro spec ones but l never found out what the differences between the two are..

 

No not really, quite the opposite.

 

That was a spam post btw... Reported!

 

^^^ Must be another one.
