Am dressing out my frame and with my big 18x8 wheels my brake kit looked kinda dinky. I asked on here a while ago if the new D52 wilwood caliper made any difference in stopping power and nobody had an answer. They aren’t any bigger but they are bright red and the do say wilwood with cross drilled and slotted rotors so we will see how they do. Had to do something with all that Christmas money LOL

Think there's a brake/suspensions section?

Anyway. I'm a novice when it comes to brakes, but I think there's multiple factors at work.

Braking power; I think a larger rotor will have more mechanical leverage. So there is a factor of "braking power", considered against the friction of the tire. But the more weight the car has, and the more it leans foward down on the tire, the more friction the tires have, but I digress. Almost any caliper, with the correct leverage ratio will clamp any tire to lock on any normal weight car - that's generally not what people are after in brake mods.

One is generally concerned with fade and weight. And that's all about dissipating heat. That is to say, hauling the car down from obsurd speeds fast is one thing, doing it repetitively is something all together different.

Iirc, the D52 is an aluminum twin piston caliper, changing up from an iron single piston? Mostly unsprung weight mod there I think - given the same rotor size.

I put them on my car because I didn't want to spend the time cleaning/painting my stock calipers. Afterwords I read they're not a great upgrade. Go to pro-touring.com and do a search, also people here said Wilwood use's the cheapest pads they can use, so research new pads.

They were primarily designed to fit behind small wheel packages. Not so much for an "upgrade" per say, but to offer an aftermarket disc brake package to work with 14 and 15" wheels.
Several years back there was enough outcry for a nice disc brake setup from those with stock wheels, and Wilwood answered.

I think most everyone with 15x8 snowflakes complains that they dont fit with 12" rotors.

Why i dont own a set

[Formulajones]

Lol, I guess so. These small D52 caliper brake kits were designed primarily with stock 11" rotors in mind for 14 and 15" wheels. Not really intended to squeeze on 12" rotors and 15" wheels.

When going up on rotor size like that, generally people are going for 16 inch wheels or larger. Some nice looking 17" snowflakes are made now that will cover some pretty nice brake packages.

Yea. Tried to fit 4th gen 12" rear rotors in a 15" snowflake out back - currently stuck with 11" there. Also no known aluminum caliper will fit - they tend to be meatier than iron units.

I digress tho

Rear discs from 79 TA really help to tow the line. You got rear disc right?

[Formulajones]

Are you set on the 15" wheel I guess?

[NBF823]

Sorry op.

Yep, ws6 rear discs, kind of a 15" guy atm

[Formulajones]

Same here, understandable.

The absolute best bang for the buck behind 18" wheels is the C6 corvette front brake, 2002 f body rear brake, 9" dd booster, 2002 s10 RHD master cylinder, wilwood prop valve combo. Its a bolt on swap, will fill up your wheels, can be done relatively inexpensively, you can use stock drum hubs and parts are plentiful at the parts store.

I run this combo. It works very well.

I wonder if someone makes the parts to fit a D52 with a 3rd gen 1LE rotor to fit a '64. That way you could use the current calipers and just up the rotor. There's a wider D52 that may fit a big C5-6 rotor, but that another set of calipers, and I think the C5 calipers are also dual piston floaters like the D52

I have the D52’s on the front of my TA with the original 11” rotor size. These did fit when I had the 15” stock turbo wheels, but now I have moved to 17’s. They use the same pads or pad size as the stock setup. I am using the EBC Yellowstuff pads and they give a great pedal feel and stop well, but they are dusty.

In the change from the OEM front setup to the D52’s, there was not a noticeable improvement in braking. The car is/was really braking well. I have the 11.6” Blazer disks on the rear.

Comparing these pads to other calipers, both OEM and aftermarket, they have a large pad area. The piston area of the D52’s is a tad smaller than the original caliper, but they also weigh 4 pounds less per side. I have been impressed with the construction quality of the D52’s. After putting on some miles on them, I took them off for an inspection and everything looked fine. I would definitely recommend them.

Well I pulled the trigger if nothing else they will look good behind my 18 inch wheels without anything too exotic. Remember looks alone add 25 HP

Yeah, this is pretty sound advice.
