My car is stock except for Koni Yellow and lowered about 18 mm (stock springs lowered 10 mm on shock bodies). This modest change has caused the thing to push like a pig. I'm looking to correct the problem with a rear bar of about 25-26 mm. Reason for such a big change is I like to run lots of front damping.

Do I need to worry about structural problems with this size bar coupled with stock springs ?

Thanks.

 

I have been using the 26mm Mugen bar for 100,000+ miles with no issues.

 

Alex 25mm rear bar here with no problems whatsoever.
