Did you change your display preference on the bottom left hand side of the page? (Display more that 2 pages)

What the GW tech support say about the UCA hitting the 17's?

yes, I changed the preference, but the thread disappeared within a few minutes of posting it. I'm waiting on a call-back from GW tech right now.

I'm hoping that anyone on here who has GW UCAs can give me their $.02.

No issues here. In fact the GW arms had MORE clearance than my stock 65 arms. :shrug:

THanks Bob. yours def. has good clearance; when my wheels are straight ahead, I have about 1/4", when they are locked they touch. I already gouged one of my wheel weights...probably need to have them balanced with adhesive weights. I put the original 14" rims & tires up front to avoid damaging anything, but the ball joint still rubs the tire very slightly.

Anyway, you're running 17x8" with 5 1/8" B/S and Wilwoods. Did you got 5 1/8" to compensate for the additional offset produced by the Wilwoods?

I'm running AR 17x8" with 4 3/4 B/S. This week I will be installing a Bear 4 wheel conversion. Maybe teh Baers will give me a little additional clearance?

When you installed your UCAs, was there anything specific you did (other than follow the directions) to promote better clearance? I already adjusted my LCAs out as much as I could to get more negative camber, but it doesn't seem to help much clearance-wise.

I appreciate the help.

Okay, I just got off the phone with GW Tech. He said the ball-joint to rim contact is due to the backspacing of my rims. According to GW, the correct backspacing for 17x8" rims to work with their setup is 4.5"

My Baer setup might give me enough additional offset to solve this problem, otherwise I might have to run spacers or install a steering stop (I don't want to lose any more of my turning radius, though).

I'm going to call Baer now to see if my kit will give me any offset.

You should definitely switch to stick-on weights. When I ran the 16's, I HAD to have stick-ons as the clipons would contact the arm. It might get you enough clearance???? As you mentioned in your other posts, 17's DO have more clearance than 16's, so this is kind of unusual....

That's correct!

I've heard they will give you an extra 1/8" in the REAR. Not sure if the front Baers have additional offset or not.

When you installed your UCAs, was there anything specific you did (other than follow the directions) to promote better clearance? I already adjusted my LCAs out as much as I could to get more negative camber, but it doesn't seem to help much clearance-wise.

Nothing special for the UCA's. Had TONS of problems with the Granada spindles and bumpsteer, but the arms were an easy deal. I've installed a couple more sets since then, with no problems on those either.

If you talk to GW, ask for "Doug Nordin". He's "the man" when it comes to tech help at GW. I wasn't impressed with anyone else on the phone desk! :(

Thanks Bob. The guy I just spoke with was "Doug." Don't know his last name, but as you can see from my last post, he seemed to know exactly what the problem was and how to fix it.

He also said that the 3/8" spacer plates are optional, and will give me a lot more negative camber if I remove them.

Nice website, BTW, and nice car. I watched your race vids a few times.

I'm not sure that I completely agree with their backspace assessment. 4.5" is correct for 16x8's, but lots of people are running 17x8 4.75" BS with STOCK UCA's, and the GW arms have MORE clearance... Mine's a good example - 5.125" BS - the .375" Wilwood track change = 4.75" backspace! :shrug:

Oh well - I'd change your wheel weights, and get the Baers on there, then see where you're at. You do have the steering stops still on the strut rods???

I've debated taking their 3/8" spacers and angle-milling them for additional positive caster. But, with the adjustable strut rods, it's not really a problem...
 
#15
thanks. I'm trying to visualize what I can accomplish by removing them.

It will essentially "shorten" the UCA, which will relocate the balljoint inboard by 3/8". That will cause the top of the spindle to tilt inward, which will slightly lower the position of the balljoint in relation to the rim, I think.

I think I'm going to think myself and everyone else who reads this right into a migraine....
 
#20
Hey Eric. THanks for replying. My original clearance (stock UCA, stock location) was fine, but now with the GW UCAs, which mount 1 3/8 lower, I'm rubbing the balljoint against the rim on lock.

Did you notice if your Baer brakes gave you any additional offset?
