Hookay! So? Question for Wayne or brake guru's

[autoxracer31]

Alright, heres the deal: I have a frozen piston in my front left caliper, been driving on it for a while and the squeak is going to drive me cruuuuhhaaaaaaazy! I am hoping to convince the folks to get the monoblock upgrade. The questions is about the brakes and wheels fitting properly. I have the original 1974 Fuchs; will the Pelican Monoblock upgrade kit fit under the fuchs? It says it will fit under 16" and I think 16 and 15's share the same core just something small adds the 1inch.

Will the monoblock kit fit under my 15 inch fuchs? yike!

On his site he states they can, I think. Bill if your reading please confirm that 15" fuchs will be okay to use the pelican monoblock kit

[KobaltBlau]

He usually recommends against increasing the caliper size without increasing the rotor size, unless you have very big/sticky tires.

You can tell us about your use, but I would be surprised if you need more than SC brakes, or possibly carrera 3.2 brakes, either with good cooling. Both of those fit under 15" wheels.

I'm glad you're proud of being a "Baller".

[autoxracer31]

The "baller" is a joke. Touchy aren't we??

I upgraded my engine to be an SC with my original exhaust so its alot faster but alot slower on braking. I want better response and an all-parts-in-one-box package to replace my front brake setup. I autocross but not to the degree that I would want some ridiculous setup. Im just looking to fix that squeak and get some faster stoppage.


PS: I changed it to Fuse boxes suck jst for you

[KobaltBlau]

Yeah, sorry. Remarking on your tag line was probably not called for.

Anyhow, you probably still have 'M' caliper brakes in the front unless you've changed them. changing to 'A' caliper brakes would require changing the front struts to the later mounting ear versions, as will any other brake upgrade. My guess is that the 'A' calipers used on an SC or the wide 'A' from a Carrera 3.2 would be as much of an upgrade as you need.

If I were you I'd find a decent (not been sitting around for too long) SC or Carrera 3.2 in a junkyard and make a deal with the guy to upgrade to that spec. Bill's site will help you find what you need.

I'm not sure - they are designed to be used with 16s, but might worth with the correct width 15s though...

IF you have 3.5" front caliper mount spacing read on. If not, go get a pair of struts with that set up first.
the following applies to new parts in terms of bang for the buck. I am sure others will suggest finding higher performance calipers and rotors, but that means more money, when those parts are new. From cheapest to most expensive:
1) new SC calipers with pagid orange (or similar performance) pads, stainless dot flex lines, ate super blue fluid, slotted or cast in hole "crossdrilled" rotors
2) new Carrera front calipers, pagid or similar pads, carrera thickness front discs, the flex lines
3) #2 plus Carrera rear rotors and calipers, pads, AND in line pressure regulator
4) Boxster REAR calipers, pagid pads (or similar), adaptors mounted on the front with your SC rotors- this is actually less expensive than #3 and the brake balance is just about perfect
5) Boxster front calipers, Carrera front discs, the pads, adaptors for front and rear, Boxster rear calipers with 911SC rear discs. - no need for a regulator
ALL the above will work without having to install spacers, larger wheels (16" or larger) or changing offsets

6) USED 930 turbo calipers, new 930 rotors, pads, flex lines front and rear- no need for a regulator. VCI will modify the calipers for you so they almost fit with no spacers and your 15" fuchs (depends how much you mill the fins down and what size fuchs you use

7) C2 front calipers (they use the same pads as 930 turbos) 930 rotors, machining to make them fit
etc etc- up thru big reds with 17" wheels and beyond

it sounds like you just need to fix your stock setup. I have tracked my targa many times with the stock M calipers. They provide more than enough braking force to lock the front tires. Add some cooling ducts and you can run in 100 deg. TX heat without fade - if you are braking properly.

I would start with route #1 that Dave (TRE) posted. This is simply rebuilding the stock brakes to stock specs and adding some better pads. Spend the extra money on seat time at your favorite DE or autocross.

[Bill Verburg]

Not to steal any bread off Wayne's table, but for that car I would go w/ Carrera front caliper and rotors w/ stock rears. You get 95% of the bang of the monoblock get for 25% of the cost. As Dave mentioned 3.5" struts are a must.

The monoblocks will fit in 15s, the radial dimension isn't the issue, the axial is, 6" would probably want a spacer(never seen that combo)

[autoxracer31]

So the main opinion would be to get 84-89 carrera calipers?
This may be really shall we say noobish but what struts and other parts do I need to do this upgrade? Does this mean need to get new shocks too?

Please help

[Fishcop]

What year cars came with the 3.5" spacing and/or is there a way to check your spacing withoud pulling the caliper?

PS I've a 69 with 'S' calipers... can I use carrera units?

Bigger brakes will not make you stop faster. If you are experiencing brake fade in a autox course, either you have really long autox stages, or something is wrong with your brakes.

I think the main opinion would be to spend the $11.75/ea for the kits and rebuild your calipers.

if you have aluminum calipers on your car, you have the 3.5" spacing for sure.
Bill
proper monoblock (boxster) kits do not require any axial spacing with any porsche fitted wheel- we have even run steel rims with plenty of clearance
autoxracer
with a strong flashlight, look thru the wheels at the front and rear calipers- do the pads appear to be the same size? if so, you have standard 911 (not S or Carrera) 3" caliper spacing

[autoxracer31]

Im pretty sure they arent 3.5's but the front calipers seem much bigger than the rears for some reason.

[Fishcop]

Thanks Dave.
