Yes and no. I've had horrible wheel spin issues since day one of owning the car, brand new Bridgestone's, (245/40/19 on the rear), completely stock car. I went and had the alignment checked and it was in spec. I then swapped in the Aragostas and noticed an ever so slight improvement (really more able to control the slide before the VDC kicks in). I'm lowered .9 in front, .7 rear so technically, I should not need camber arms as I should be able to get it in spec.
My front tires are now gone on the inner edge, in six months, and I most likely could have gone another four months before replacing if the alignment had been better. Aftermarket upper control arms have already been ordered as I'm not replacing tires every six months. I don't know if it's a camber or a toe issue. I do not have a good suspension/alignment shop and no one with corner weight scales. I've set the shocks to Aragosta's recommended height as a result. I have a highway jaunt at least five days a week, 25 miles or so.
My rear tires are wearing far more evenly. But the traction issues still persist.
I'm pulling the trigger on new wheels, 19x9.5 and will run 255 series Michelin PSS's. I know they'll help a bit based on reports from other owners switching out the OEM Bridgestones. They're about 3/10th taller than the OEM rear wheels so I'll be able to drop the car ever so slightly from where it sits now.
My real reason for purchasing is that I want to be able to optimize the alignment and not have it compromised by my ride height (as modest as it is) and try to determine the best alignment balance between cornering and acceleration (straight line and coming out of corner). It's a 7AT. I can switch to manual, slide into second gear and floor it. It'll just spin the tires up. Pretty much the same in third. No wheel hop. Car handles fine otherwise. For toe, I guess the traction bars are the solution as I don't want to use the toe bolts and elongate the slot. Plus they slip.
Here's a chart (it's a little hard to read) from my last alignment after installing the dampers and lowering the ride height:
I have two power adders and no tune currently as I don't see the point until I get my traction issues under control. A Corolla would own me off the line. So something's not right. I just need to figure out what.
Edit: I've also messed with tire pressure front and rear.
