ive always used a normal metal grinding disc.. works great.

btw, i know it sounds obvious, but dont breath in the burning rubber, and wear long sleeves... i usually grind metal with shortsleeves without a problem, but the rubber likes to smolder a bit so it hurts more when it hits your arms.. lol.

Do Not Cut The Bumpstops. Not Off The Car, Not The Mounting Location For Them Off The Car. The Car Uses Them, And They Are Not Detremental To Performance

you have to trim the sides of them to clear big tires for drag racing. you dont cut them off or remove them, but you just shave a little off the metal edge that hangs off the side, so it doesnt rub the sidewall of your dragslicks.

i wouldnt recommend anyone remove them completely.

Easy there Sam...people do this all the time to clear big (wide) wheels...they are just trimming, not taking them off.

Actually, if you look in the wheels and tires section, there are a lot of people who grind them down or remove them completely, which is wrong. The logic is "the tires will hit the wheel well before the bump stop, so they're not necessary".

I'm not fighting that fight, though. I trimmed the mounting bracket back a little for clearancing the rims, but the bumpstops themselves are still very much intact.

Yeah, I've read that too...but I don't really consider the internet crowd to be a majority, no matter what it seems like. I'm talking about other people I know locally.

I just get tired of trying to fight with people who have convinced themselves of something that isn't correct. Sam has far more patience for that than I do. I love helping people with detailing, but I don't know enough about much else to give out advice, just personal experience and what people I trust have told me.

Yup, trimmed the corners of my BS brackets when I went with 17x11 wheels. The wheels didn't hit while the car was at ride height on the ground, nor thru suspension travel (that I know of), but when you put the car up on the rack and let the rear hang - the wheels would lock up solid against the BS bracket corners.

I even had one moron try forcing the wheels to turn the first time this happened and the car was up on the rack - nice gouges on the inner lip of both wheels

Would never remove them - they're for a purpose...

And yes, I just used a Angle Grinder with a standard metal grinding disc.

same here.

besides, if you actually look at teh wheel well, its obvious that they protrude inward more then needed and hit big rubber... just grind down the side a bit, and it all fits. bumpstop stays intact.. its just thinner on that side.

I have to grind in the circle location. The actual bump stop I have to grind down a little bit too, but the bracket, and the fender where those bumps are have to be ground down. I ordered adj. LCA's and PHB with SFC, maybe the PHB and LCA's will help center the **** out, the LCA's give SO much more clearance then the stock ones.

How much better '60 times can I expect with SFC, adj. LCA's, adj. PHB, and 325/50R/15 Nitto 555R's in the back? My best '60 was 2.0790 on street tires. If I ran a 13.4 with a 2.0790 on street tires, what can I expect with drag radials, 200 lbs. weight reduction, and better suspension?
