looks like most people have gone aftermarket to correct most of their suspension problems. Just wondering if anyone looked into / have also done this to their vehicle per TSB. I understand it can be a bit cheaper going after market adjusters to correct alignment issues. Like i said just a heads up if anyones done it this way also.

I myself have this problem and looking for best fix. Moneys not a real issue since these cars are 20+ yrs old and things get worn out. Any idea on whats different w/ these new arms / design ?

Anyone have a part number on these arms?

Part # FCY1 28 300 Lower rear (R)
Part # FCY1 28 350 Lower rear (L)

It's more than a bit cheaper to go aftermarket. I just looked up those part #s on Mazda Motorsports...OUCH! You're looking at over $1k for a pair of those updated arms...

 

If those arms have 1 degree less negative camber built in, those could be a great part for EP racers who use bias ply cantilevered slicks and require virtually no camber in the rear. I'm assuming that wording before is refering to 1 degree more positive camber, which is only natural to fix excessive negative camber.

 

not suprising...
