Would probably need. The caliper cage though

**Captainfab** · 04-03-2010, 12:45 AM

The LS1 rotors are 12.01" in diameter and 1.02" thich which while being bigger in diameter are thinner, which may not be an issue. The center register hole is 2.78" whereas the truck axles require a center register of aprox 3.08-3.10". So a machining process would be required. Then the bolt pattern is 5 x 4.65", so the 5 x 5" pattern would need to be drilled. The shallower depth would lend itself to a simpler less expensive caliper bracket, but I don't know if that would be enough to offset the cost of machining the rotors.

No, the Impala SS style caliper is completely different than the D52 style calipers. I didn't spend a lot of time reading on the Impala SS forum, but they were talking about front brake upgrades, not the rear. I used to make a bracket for the Lincoln rotors and the smaller GM Metric caliper. I have since sold out of that design, but I plan to develop a new improved desing in the not to distant future.

Um, obviously I would like a set too.

suttoncurt · 04-03-2010, 12:31 PM

Ok - i'm in captin fab - Let me know your ideas on running the brake lines to the calipers on the rear end . And you can send me a invoice thru paypal suttoncurt@yahoo.com

**Captainfab** · 04-03-2010, 11:52 PM

Yeah I assumed you would want a set Chuck.

Curt, I'll post up some pics of the final parts here before sending any invoices. That way you guys can see exactly what you'll be getting. Thanks for committing to a set.

So that makes 4 sets.....

Got some parts ordered this morning......

Anyone know what years of astro van rotors will work ? I'm thinking as long as its the awd model it doesnt matter?

**Captainfab** · 04-03-2010, 11:49 PM

The rotor you will want is Raybestos #580442RGS That is the one I am using for mockup.

smashingchuck · 04-09-2010, 01:45 AM

wow, those look great! Do you think using countersunk bolts would reduce the strength too much?

**Captainfab** · 04-09-2010, 01:59 AM

Thank You

I wouldn't think it would. I believe flat heads are typically GR8 anyway.

staggerd86c-10 · 04-09-2010, 07:56 AM

that does look great, i was wondering are the calipers more or less clocked to look like if they are in the same position of the front ones? so did you break down a final price? If im not wrong we would have to remove the axles to do the swap anyways right? i thin thats the only way to remove the backing plate for the drums.

**Captainfab** · 04-10-2010, 01:56 AM

Yes the calipers are up at about 2 O'clock which might be a little higher than the fronts. The final price on these brackets remains the same as I posted above....$232.00 plus a flat rate shipping of $10.00 in the USA. Yes you will have to remove your axles to remove the backing plate. However these conversion brackets can be removed from the housing without removing the axles again.

I'll be curious to see if these brackets will work with the dual piston design of the Wilwood caliper. The brackets look GREAT!

The D52 willwood is a direct replacement for the GM D52 .

Oh, I know that, but I was just looking at how this bracket seems to follow the shape of the single piston D52 caliper, where the overall shape of the Wilwood would seem to be different due to the dual piston design. The factory spindles and aftermarket spindles have a much larger open area than this bracket is all I was concerned with. Do not get me wrong...the piece looks phenomenal, I just was wondering out loud about the relief size where the actual caliper body fits.

**Captainfab** · 04-10-2010, 02:00 AM

If there was a clearence issue, I would do whatever it takes to make it right. Smashingchuck is sending me one of his Wilwood dual piston D52 calipers to test fit. So we should have a comfirmation on those in a few days.

Thanks.
