[the real shocker]

I recently purchased UPR upper and lower adjustable control arms (Part Number: # 2002-02 and Part Number: # 2001-2). My buddy and I went to install them today only to find out that my stock bolts are entirely too big for the holes on the control arms. I talked to someone there at UPR and he told me that I have 2 options. I can either drill the holes on my new control arms to a 14mm bolt size, or I could use 12mm bolts. Well here is my dilemma... I would not have bought the control arms had I known I had to do drilling on them, thinning out what little metal there already is. Also, if I went the other route and chose to use 12mm bolts, I would imagine it would be quite noisy have 12mm bolts roaming around in my 14mm holes on my car...and quite possibly hard to maintain a steady pinion angle?

I have purchased several items from UPR and have been pleased with everyone of them up until now. Perhaps yal can steer me in another direction because I honestly do not want to drill them out. If that were the case, I would have ordered some cheap brand and went to town on my drill press. I prefer not to have a noisy rearend from mismatched bolts and holes, seeing as how this is my daily driver and it sees quite a lot of road time. I really do not want to return them because they are nice control arms, and I am ready to have them on!

Any one else had these problems?

cant you just go with a 7/16 or 1/2 in bolt?

[the real shocker]

well I had received the wrong pieces

Just got off the phone with UPR again and they are shipping the correct bushings now :yup:

Thanks guys

so they just sent you the wrong bushings? and the ones for the car bolt up with out any trouble? i was just wanting to know b/c control arms are prob gonna be my next mod. let me know how they do

[the real shocker]

yeah, they has mistakenly put foxbody/IRS bushings in.... i also found out the upper control arms use the 12mm bolt... So I could have installed the uppers, I just didnt bother after the lowers werent right.

ok well my next ? i read somewhere in a forum that if you want to help hook up during launches yea the control arms help but if you want a better handling mod the after market control arms are too stiff, now i could be wrong and misunderstood that statment

Well i would think that they would help your handling i mean your replacing the control arms b/c they flex under hard launchs so wouldent they flex if you were cornering really hard. they should help reduce body roll in turns to some extent. I could be wrong.
