Default Question about brake conversions

I found on craigslist a full set of brakes and rotors from a 2002 Porsche Boxster S. I have an early 1985 944 and was wondering how easy or difficult it would be to do a nice reasonable brembo brake conversion on my car. Any thoughts on this? Here's the ad: http://sfbay.craigslist.org/sfc/pts/2247721001.html do you think this is a fair price for these?

The radial mounting bolt hole centers are 130mm and the front calipers take a 318 x 28 rotor that is 67mm offset. The early NA hub bolts a rotor to the back, so if you keep those you'll have to build rotor hats. The rear Boster S calipers will fit an 86T rotor perfectly if you build an adapter for them.

How difficult do you think this process will be, and how much in other parts would i need?

You have to be a machinist and have the proper equipment. Having them fabricated could cost you lots of $$ as well.

I did a 86T brake conversion on my '86 NA and it came out around $800 - 1000 for '86T calipers x 4, front spindles/hubs/rotors, rear rotors and the front strut assemblies. All parts were used. I track the car but these brakes are overkill for a NA 944.

If that option doesn't work for you, you can always do this: Rennbay Big Brake Kit

if you want super brembo brakes, buy the strut/spindle/hub/brake setup off an '86 turbo and bolt it on...

You'll need at least 16's for the turbo brakes.

The Rennbay Big Brake kit works really well. Straight forward bolt on kit.

What is it about your current brakes you wish to improve upon? Feel? Heat/Fade resistance? "bling" factor?

Do you track your car? Dropped in an LS1 conversion?

Sometimes putting in fresh, high temp fluid and more aggressive brake pad compounds can do a world of improvement. Also consider that since your brakes are only as good as your tires.. how's the rubber that touches the road?

I thought that I would need 16" wheels when I did my conversion but SURPRISINGLY enough my stock 15" Phone dials clear them with no issues!

What are the part#'s on your 15" phone dials. I heard that 15" phonies with 951#s were rare but fit the turbo brakes. I have a spare set of 15" ET52 wheels tires that I was going to try on my Wilwood NA kit with the same 298mm rotors, but 32mm thick.

The Wilwood Renbay kit should be just fine with the 15" phones. I had 15"phones (early offset) when I did my Rennbay kit. No problems at all.

I love the 86 turbo brakes on my car. More than enough brakes for this car, with that said, these are momentum cars, you shouldn't be using your brakes anyway.

I can check the part numbers but they are the stock 1986 944 early offset (23.3mm.) 15" Phone dials
I was pleasantly surprised when I tried them out, after the brake upgrade, and they actually cleared the calipers without any issues. No spacers either.
I am using 2 sets of them for the track.

yea i plan to eventually do an LS1 swap, but for now bigger brakes are nicer just because the bigger, red brembos look better under the wheels. V2, what is the strut/spindle/hub/brake setup? and how much does that cost?
