I had my rear wheels off yesterday to check out where to cut my Flowmasters off for my new Magnaflow, and I realized that the UCA's are right there and pretty easy to get a wrench on once the exhaust is off. How hard of a swap would this be in my garage on jack stands?

What UCA's would you guys recomend? I already have the X2C lowers, and this car will no longer be my daily driver in a few months so I'm not worried about ride quality. I'd like something adjustable so I can set the pinion angle. Should I go with poly bushings or solid?

Thanks,
 
The uppers are real easy when you have the other crap out of the way. I did my lowers and uppers on jackstands in a little under 4 hours. I have pro3i and love them, but only my lowers are adjustable. I don't know if pro3i makes adjustable uppers, but if they do, I'd recommend them. People really like Maximum Motorsports stuff too.

On another note, I did have to file down the shaft that runs through the upper bushing on the upper control arm for the passenger side. It wouldn't slide in otherwise. I just took a grinder and filed it down a tiny bit and it went right in. This set me back about half an hour too.
 
I just did my UCAs last weekend and it wasn't hard but just annoying. You have to drill or torch out the bushing on the axel end. I drilled and used a screwdriver. Takes some time but not really hard. The only other somewhat difficult part is finding the right jacking point on the axel to get the bolt holes to line up again. I say go for it.

BTW I have the Steeda heavy duty uppers.

I recommend NOT using solid bushings on the chassis end. Only rubber. Also if you just install the UCA's and leave the stock axle bushings in it won't improve anything.

I agree, the stockers will only tear. I just had mine rip and now I am replacing them with UPR Spherical Bushings and installing Torque Box plates for preventive measure. Only one more piece in order to complete my UPR Pro Street Rear suspension.

Any reasons? I had D&D motorsports just e-mail me and say they'd be OK with solid bushings in the LCA's.

Why would you install LCA's and leave the stock bushings in :shrug:

Solid on axle end, not chassis end.

I was refering to the UCA's, either way LCA's come with new bushings, unless where you are buying them they are cheap-asses.
 
Uppers were a pain for me. The stock bushings were melted due to leaving my tailpipes off the MAC cat back. It took me days to get that crap out of the rearend. What a mess.

It's time consuming so have patience.
