Does anyone still carey the large M2 rear brake kit with the option for a street e-brake? I wa s looking at that a couple of months ago and now I can't find it anymore. Are there any possible replacments for this?

I don't think anyone has a rear brake kit that lets you retain the parking brake. You'd have to get something custom done. I know wilwood makes an additoinal small caliper you can add to an existing big brake kits that you can use as a parking brake.

I don't think M2 is in business anymore.

The RZ rear brakes are a little bigger in diameter and retain the stock calipers. Works fine for my street/track FD and for many others.

So I am the only one that saw that? I'm pretty sure I saw it on the rx7store.net website a long while ago probably last summer or so?

The 99+ RS/RZ rear brake setup will work great.

I remember that the M2 kit had an option to keep the parking brake, but I don't think anyone ever got one. I think M2 looked into what it would take and decided not to move forward with it. The rear caliper in their kit did not support a parking brake, but rather it was going to require a separate mechanical spot-caliper.

I have a rear setup that uses a Wilwood NDL caliper, but I don't have a parking brake. Not having the parking brake has turned out to be pretty easy to live with for me. I just put it in gear when I park, and the car has never rolled anywhere. You do have to be careful with how steep of a grade you can park on, but I have always been able to find a reasonably flat spot to park. I suppose you could keep a wheel chock (sp?) in the car (there is a stock one in the back of the car anyway) if you can't find a flat parking spot. Here's my web page about my rear brake setup (and I have some Precision Brakes 2-piece RZ-style rotors waiting to go on as well):

I asked David from Widefoot (the supplier of my caliper brackets) if a spot-caliper parking brake option was possible, and I guess it turned out to be more trouble than it is worth. Widefoot doesn't offer anything to keep the parking brake, and I don't think they are planning to. I don't know of anyone using a spot caliper on the RX-7.

If you must have a parking brake, I agree that the RZ setup (with the Mazda caliper) is your best bet.

thanks you guys

At least in NC, a parking brake is required by DMV regs. Whether an inspector would notice is another matter, but if your car rolled downhill and was damaged, or damaged anything else, I suspect your insurer would use noncompliance with the reg to deny coverage.

I've been driving a stick for over 10 years and I have always used the parking brake. I always felt that leaving the car in gear to park would cause some sort of stress on the trans. Am I totally wrong here?

I think it depends on if you are on a hill or not.

Xeros, save your money. Between this and the 'increased throttle response throughout the entire power band' thread, I think you may be looking at spending your mod money in an inefficient way

If you want a rear brake kit that also keeps the hand brake, we are working on one right now. The hand brake part can also be used on all kinds of aftermarket rear brake kit, including our Brembo one. How many of you will be interested? The price will be around $400 for the rear hand brake kit.

What do you mean when you say inefficent? Just curious. I ask these question because I already knwo just how powerful the car is so I dont really plan to pour money into Giant power mods. I dont really need it to go over 325 hp. Nor will I ever most likely. I just want to improve performance with in that power range. Wouldn't you agree that a very effcient and super responsive car with super small boost lag is better than a super high horse power car that has massive lag when it comes to things like auto cross and what not?
