Installing adjustable upper control arms

Post by **kingQong** » Sat Jul 30, 2005 1:55 pm

I'm having my shop install adjustable upper control arms on my 91 Q. My dumb question is, what is adjustable and what should I set it at?

My ride in case y'all forgothttp://nissaninfiniticlub.net/...t=500

The upper control arms adjust camber and the alignment guy will have the correct settings. I hope you aren't getting the ones for the 300ZX, as they are shorter and may not have enough travel to do you any good.

Replace the php tags with img tags.

Hope they are not the Stillen upper links. The links control the camber settings. 911/Q45 had not very nice things to say about his, as others have ditched them also.

See you have the 17"x7.5" FY33 wheels. Be sure to have them checked to make sure they weren't part of the recall if you haven't already.

Don't worry about difficulties posting. I can't even post on member's Rides as it continually shunts me back to the log-in page when I try to upload.

Did anyone mention chain guides to you yet?

I replced the php tags with img tags as maxnix mentioned.

Got no idea on the "adjustables"

I have 300zx TT adjustable upper front & rear control arms on my Q. No problems with alignment. I also have the Eibach springs & Tokico blues installed & 300zx TT solid/adjustable tension rods. 18x8 front & 18x9 rear wheels. No bad tire wear. Guess it just depends on which adjustable control arms you use. I have Midori fronts & Stillen rear upper control arms.

The FRONT oem center of camber for the tire designed to be used [Sport XGTV] was negative 0.75 degrees. Depending on the tire you select the camber setting SHOULD vary...............as you go up in size [stiffer sidewall] you might try 0.5 negative.

IF tire life at the expense of peak handling is desired you can set a larger wheel size at ZERO front camber [on 90-96 Q only] as there is built in negative camber gain as the suspension compresses.

Unfortunately softer sidewall all seasons require more negative static camber to maintain a optimum 0.5 degrees under turning load/slips. Some tires may need as much as negative 2.5 degrees to stay perdendicular in cornering.

Lower cars are a problem as the camber goes more positive up thru the 1" rise [after a rebound.

Me too... The stillens dont have as much area of adjustment, but the SPL (midori) ones have a LOT of adjustability.....

I believe mine are midori, and I am not that concerned about tire wear, I put minimal miles per year on the car. Currently I have 244/45 17 Dunlop SP9000 (which I love, btw) and change in the winter to different tires

adj. upper control arms, driver side king pin and front strut tower brace installed. I feel like I am driving a new car. All smiles

I put new shoes on Lola today, and tried to get the camber adjusted. The front is non-adjustable, and left is -0.7 and right is -0.8. The rears are a little adjustable, and they are set basically the same. I had them set the toe-in to zero.

Maybe my 18" tires will not wear so bad, now. 20K miles, and the inside edges were shot. Of course, those were 245/40/18's, and I now have 245/45/18's.

They fill the fenders much better now, too. She doesn't look like she has a lift kit on her anymore.

Hi, Jeff.

Which tires did you get?

I recently installed Goodyear Eagle F1 GS-D3 245/45-18 100W on my M45.

Inside tire wear is due to poor toe, not usually camber. Outside tire wear, on the other hand, is usually due to too little camber for an agressive driver. You can guess which one I always have problems with

Continental ContiSport Contact ZR18 96W.

I bought all 4 off of eBay for $265 from some Infiniti dealership. I only ahve 5 miles on them, and they are SUPER quiet and ride WAY better than the Sumitomo HTR+ Of course a 245/40 vs a 245/45 is a big change. AND new tires always ride better than the worn out ones you replace.

The last Continentals I had were 235/45/17 on Layla. They were not too good, because the inner sidewalls are much weaker than the outer ones by design. The inner sidewalls are the ones the Q needs to be the strongest, due to the severe negative camber of the stock system.

This set are more equal. The outside is labeled, but it looks like it is just for curb protection.

What do you think of the F1's? The runflats on the Corvette are quite noisy and harsh.

If you can wear out the outside of the tires on the Q, you ARE pushing that thing!

I haven't had it long enough to know, but my previous experience is with Mac Strut cars so hopefully the Q won't be as bad.

FWD or RWD? Big difference.

Both, with all kinds of suspensions from stock to coilovers and everything in between. Any car with Mac struts won't gain enough camber in roll and will chew the outsides off the front tires. Of course FWD will do it twice as fast, but it's been my experience that even a RWD car with not enough camber and a Mac Strut suspension will have excessive outer tire wear. I had a '64 Dart with modified (shortened) upper control arms and taller spindles that had MUCH better camber gain in roll and did pretty well. I just hope the Q has similar geometry.

I don't normally keep cars long enough to go through more than two sets of tires. By the time I've modified the suspension to the point that I'm happy I get bored. I've done just about everything by this point so I've got quite the dilemma with the Q. I might just leave it stock!!!

What in the heck are php and img tags and what is the difference/purpose?
