Have narrowed down to Metco or J&M UCA. I know the difference in design and how each addresses the clunking and binding problems.

For street use. Will use adjustable, eventually will install lowering springs Any input or past experience with either will be helpful.

Never used either. I prefer CHE or Steeda.

I got to handle the new Metco one at The NMRA Bowling Green race. Very nice! I ended up buying the Metco LCA for my GT500. I'll probably pick up the adjustable upper at PRI.

the UCA is also for my 2008 GT 500. Am just starting to upgrade rear suspension. Have Penske 7500 series single adjust rear shocks on the way. Will install shocks and UCA for a beginning. Do you think the Metco UCA is better choice than J&M

My 07 GT has FRPP lowering springs and Tokico D adjustables, and J&M adjustable UCA. The UCA is adjusted to the maximum setting to get the pinion angle back a more desirable angle. If the Metco UCA has greater adjustability I would say go with for that reason. Other than that the J&M UCA is a sturdy and beefy piece. The pictures of it on the website don't do it justice. I am happy with it.

I have the J&L lowers but they didn't have the upper at the time or I would have bought it. The lowers work great.
