I've been lookinging around for a brake upgrade kit for my '89, unfortunately I've discovered that brembo only makes front brake conversions. does anybody know of a company that makes 2-piston caliper, vented+slotted or vented+crossdrilled rotors (or better) brake conversion kits?

 

2 pistons....? arent the original calipers on 7's 4??

 

single piston calipers stock.... they are ok for street.. but not much else

 

The TIIs and some n/as had 4 pistons in front. You should upgrade to those and get some good pads. Should be enough for you I'd think.

 

ah ok was thinking of the t2's thats why

 

corksport sells a brake kit but it's right around $3k for it all

 

if you were going to upgrade to the t2 calipers, would you have to do any other work to the brake system?

 

i can get really nice stainless steel lines. have them on my car. from Stainless Steel brake Company

 

repeat again...
drilled rotors is not an upgrade

Technically, no. However, most people snag a TII master cylinder as well. The 4-piston calipers take more brake fluid to actuate, and the TII master cylinder pushes a bit more fluid. Your current one will work, but it will take more pedal travel to stop the car.

cross-drilled = weaker, only a tradeoff if you have oversize rotors and are fanatical about weight ( totally unecessary on your car )

slotted = prevent fading, but wear pads faster. Look cool, but unecessary if you drive street.

Save your money- stainless lines and good pads are all you really need. If you want to dress it up, paint up the stock four pot calipers.

Done.

 

^^^ excuse the ignorance, so unless you go with a bigger contact surface (oversize rotors) cross drilled and/or slotted are a waste? I know cross make them weaker... and slotted ate up your pads but they are not beneficial in stopping your car any better?

 

The slots prevent glazing, and merely keep your brakes more consistent during hard use. As far as stopping better, make sure you have good rubber on those rims. The tires actually stop the car, not the brakes. Most other mods are made are for brake feel and reliability, not stopping distance.

 

i did t2 upgrade.. pretty easy... although my hawk pads that i had on the regular brakes didnt fit .. lol oh well no i have hawk pads and they woprk great with ss lines... still have the same cylinder and travel its bad.. brakes way better than my 240sx that i used to have..

 

so it's pretty necessary to upgrade to a t2 master cylinder?

 

I believe some rx7 vendor offers or used to offer a 929 brake master cylinder upgrade kit for $150. I cant remember who though.

 

Theres a good thread in the suspension/brakes forum or racecar tech forum. I forget which one but basically from what I've read, crossdrilled offer no performance benefits for today's modern brake pads.

 

If slotted/drilled rotors are not beneficial, then why does all the retailers of the product state that "Upgrade" from your stock rotors=better braking, less wear on pads, blah, blah, blah? Also, then why do the $50 grand + cars running slotted/drilled rotors? Anyways, just wanted to share my 2 cents.

Hope I didn't **** anybody off.

The way I look at it, slotted and drilled rotors reduce the contact surface, causing less friction. Why would they stop you better?

 

"blah, blah, blah" is the key phrase here. It's called marketing.

well we can go round and round about cross drilled rotors but if they were no good and didn't help with performance then why does Porche and you high end sports cars use them year after year. Porche does put a damn thing on their 911 that doesn't have to do with performance. Its all up to personal liking. If you like them get them. **** ebay has brembo fronts and bradi rears for 190 bucks a set.

 

They do help, on cars that are made to experience heavy braking. F1 cars use them, but look at how much wear they get. As do Ferrari's. However, our cars are made for occasional high speed runs, drifting, autox, but also city use. It's easier for a company to make regular brakes reducing the chance (almost completely) of fade in regular everyday driving. Think in sensibility, not marketing.

 

WRONG.
They used carbon-carbon discs which have no cross-drilled holes on them.


Cross-drilling is something that was a myth that most dumb consumers wanted - supply and demand.
Some cars (i.e. Porsche) used them cause the brakes were already oversized, and drilling them did not cause their braking performance to suffer substantially to worry about.

It has a link to the original GRM article that was written a few years ago.

You're another one...

It's all explained there.
If you're still going to disagree, then why bother arguing...
