BMR SP080 Alignment Specs?

[BmacIL]

BMR 089/082 lowering springs, with some advice from BmacIL for alignment, also making sure you clock the bushing,,,,,Very happy with results.

That is a great alignment!

Yes, have them set it to Kelly's specs. Do not be OK with 'in the green'...you can have a goofy handling car with every spec in the green. Make sure it's extremely close on toe angles and within +/- 0.1 on camber. You will not see adverse tire wear. Toe is what really wears tires weird, not camber unless it's very, very high. One modification I'd make is to go closer to 0.00 up front for toe on both sides, but 0.05 in will be fine too. For track use go up in camber to around -2.5 front, -1.75-2.0 rear.

Thank you sir!

Sorry to necro this thread but what are the alignment specs on the SP080s to mix between a street and drag setup? Right now on my 275/35/20 fronts, 20x10" +35, it rubs on occasion but the camber is at 0 degrees right now in the front.

I run skinnies once in a while so I'm looking for the best spec to mix and match between the 26" tall skinnies and 20" 6GR fronts.

Thanks

camber is at 0 degrees right now in the front.

Why? That's a terrible idea for a street driven car.

Use these:
Front camber -1.2
Front toe 0.00-0.05 deg per side

Rear camber -1.0
Rear toe 0.05-0.08 deg per side

Rear camber -1.0
Rear toe 0.05-0.08 deg per side

For drag applications, BMR is recommending 0 degrees of camber in the rear. I see they recommend -1.25 for handling so should I ask for something closer to the middle like -.6? Or do you think -1.0 really is the best?

Zero degrees rear camber . . . not a good idea for any IRS car that sees street time. Especially in combination with dragstrip shock/strut/tire pressure tuning, which typically shift the handling balance in the oversteer direction as well.

For dragstrip-only use (no street driving at all), I'm not at all sure that 0° would truly be the optimum setting unless you're measuring that at some amount of squat determined by actual timed testing.
