Made some rear bump stop relocation brackets

[ZOMBEAST]

EDIT: Go to post # 90 on page 4 for the latest pricing and product info



So I finally got around to removing those big bump stop brackets that would interfere with my widened stock wheels when jacking up the car. I decided I wanted to try and retain some sort of bumpstop out back. I came up with the brackets below that relocate the bumpstops. They relocate the bumpstop so it lines up with the frame rail. The frame rail is narrow, but this should work fine. I drilled a larger hole in the middle that just overlaps the hole at the stock location so air can escape during compression. Pics below are rough cut that I'll shape later on a table grinder. I used 1/4" steel.

That is Nice!!

Do you have a template or are you willing to make a couple more for some $$$?

Thanks, R

You should patent these and sell them. I would buy a set, as would pretty much anyone wanting to run wider wheels or large slicks at the track.

How wide of a rim/tire can your run with this setup... I'm very interested...

 

[kent1]

Nice setup and great thinking.

 

[bull3441]

that's good old fashioned American ingenuity right there. and to think i spent two hours putting my damn hood vents in LOL.

Seems there's some interest in these on other forums. I need to check with a local machine or welding shop to see what they'll charge for some blanks. I can't cut stock this thick at home.

Not sure on other size wheels, but you can do 8.5" back spacing on an 18" wheel with no issues on a stock height or lowered car once you remove the old brackets and shock dust boot. Anymore back spacing and you'll have to mod the lower shock, and run a narrower tire which kind of defeats the purpose.

This is a 12" Alcoa..............

BTW - For those who are using Alcoa's, that is a 10" on the front.^^^^^:thumbsup:

Please let me know what you machine shop guy says.

Thanks, R

Robert, I bet those 12" wide Alcoas weigh a ton. lol

Probably, they are definitely heavier than the 10's that came on the car originally, but I have also added a much larger rear tire to the equation. What would a 2" aluminum band weigh that is added to the inner diameter? That is the real weight that has been added to the wheel and the original forged Alcoa was not a heavy wheel to start with. I would suspect that a 2" wide band in aluminum around the inner diameter is not excessively heavy comparision to the traction gains of a 325 or 335 rear tire. Without traction, the rear wheel weight is not real important, because you are going nowhere in a hurry while the car with traction walks away. The set up looks massive, because it is, 12" of tread/traction surface.

I should have weighed the wheel when I got it back from Weldcraft.......

Here's a finished piece. I gave this to the machinist today. I should have a price this week.

EDIT: Design is being tweaked just a bit. Should have a price with hardware and shipping next week.

Looks Great. Please put my name on the list.

Correct you are, and the reason why I don't worry about the weight of my 18x11" setup with the MT 345s. Before, I spun in 3 gears, now only in first.

 

[09Troublemaker]

Very nice thinking/design. Can you say patent lol;-)

I don't see how the bumpstop itself will aid in tire clearance, as the bumpstop is not the issue with wider tires.

:dw:

Relocating the bumpstop allows removal of the bracket that interferes with wider tires.

I cut my bracket but left the lower portion in tact, as many others have done.

 

[DavidHasselhoff]

So this is all I'd need to run a 19x12 or 20x12 in the rear? If that's the case then I'll buy a set of these.

Yes, and then the bracket can be cleanly removed back to the frame rail.

I have a picture of yours also.............
