Wedge Drilled & Slotted TR8 Rotors - anyone?

Share this page

$500 bucks!!?? :crazy: :sick: :wall:

ouch.

my budget says we would be looking around some more.
 
Drilled and slotted rotors for street cars are more for show than function. Most of us don't get on our brakes enough for them to get so hot as to create the gases that the slots and holes are meant to combat.
Have I used them? No. Have I researched them? Yes, and I wouldn't pay that kind of premium when stock units would provide the same performance at a better price.
 
I bought stock ones for my Spitfire and taught myself how to use our CAD mill to put my own slots and spots on them. I have the green stuff pads on it too. Can't say I noticed a difference, but then it was 7 years between parking it and using it again. .117 between the big one and the stock ones is a pretty wide spread, I'm impressed the calipers can cover that kind of difference.
 
PS, GBC is a relatively new name, but I haven't heard anything bad about them.
 
I have EBC rotors (cheaper non-vented style) on my TR4 for about 2 years now and they are fine. EBC makes the Greenstuff pads. And I agree with Doug, this was just a bling add on I picked up at a decent price, not a performance mod.
 
I bought new ones for my TR8 from Woody at the Wedge Shop. They were part of the package with Wilwood new calipers, so I don't know the cost breakdown, but it should be on his website if you are interested.

I do have a very slightly used complete Rimmer Big Brake conversion with like new rotors and pads and even extra new pads & clips if you want to convert. You will need 14" wheels to do so. I'd sell them reasonably including the spacers for the front wheels.
 
Randy, if you go the 2 wider versions you'll have to add calipers. Don't think the stockys will fit that width.

Just my 2¢ - most drillings are angled straight through with no effort to break the edges. The only "bad" I've heard about drilled rotors is that cracks can occur between drillings. The surface area increase for heat dissipation is very small, so I wonder if there is any real benefit.
 
I've had several cars with drilled rotors. All cracked at some point. I do autox and drive hard on some twisty roads, and never really noticed a difference. Well bled, properly adjusted brakes are good, add really good pads and they are great. Also, the best way to increase braking performance is to get stickier tires. Most people overlook that detail. Save your money, set the brakes up properly, and get better tires. I'll never use cross drilled rotors again, unless I'm running an insanely fast track car that the rotors turn orange on in turns.
 
Thanks everyone. Great insights. It looks like these aren't cross drilled. Just dimpled.

I don't drive the car very hard and the advice of better tires is probably a good one. I have Cooper tires right now and they are not very good.

Unless I fee a need to experiment, I'll probably get the standard rotors at $90.00 and upgrade the tires in the spring.

I have the EBC pads on the car now and they work well, so there is some confidence going forward using their rotors as well.

Thanks for all the feed back.
