Who's run 28x10.5W's with stock LCA mounting points. Tell me what you did to make them fit.

The Big Fucking Hammer Method Works well.

Needed to rid myself of the bumpstops as well, but everyone's car seems to be different. Mine's LT1 as well, could make a difference. I tried to get away with a little 5lb handheld sledge, but I think I need to have at it with a full-sized. My car just isn't crazy about accommodating these tires. :)

John, put them on for the last time out this year a few weeks ago. The fascia was already trimmed for 28x10.5's and the bump stops had also already been removed. The LCA's are tubular (stock mount points) with the rear centered with an adjustable panhard. The front inboard of the wheel well near the LCA's was hammered inward a bit long ago. Fenders have not been rolled, but rear shocks run fairly stiff with stock springs and have not ventured into the tires, either these or the "plain" 10.5's.

That said, for the W's, surprisingly, they fit on the 10" rims (6.9" bs) with out issue, but it is REAL tight everywhere...I would not go around the turn off at the track too darn quick. Take care. Dave

For a 28x10.5W on a 9.75" 'gart...
-say goodbye to the bump stops
-trim off the leading edge of the rear bumper
-beat the hell out of the front corner of the inner wheel well
-roll the fender lips
-beat the metal around the spring pocket like it just stole your lunchmoney

I also got some tubular LCAs and offset them as far in as I could (1-1/2" or 1-3/4" I think). This made a lot of room.

In hindsight, I should've just got the torch out and mini tubbed the sumbitch. :lol: When you try to beat down several layers of metal, you either need to heat it up and work it that way, or get REALLY angry. I did both. ;)

How much did you narrow your rearend? I'm thinking about narrowing 5" and running 6" backspace alumastars (tucking an inch per side)

Mine is Narrowed 3" Per side, so 6" Total, I will run a 15x10 w/ 5 BS, from my measurments it will tuck the wheel in .5" more than stock

3" per side.

I can run w/o a spacer and move the LCA's over in the stock loactions, or run a 5/16" spacer and run the LCA's centered.

I've got an extra set of Alumastars (non-beadloc) that have never been run if you're gonna narrow the rear :)
