Awesome car!

How is the clearance between your tie-rod ends and the brake rotor? I had a clearance issue there with the 949 BBK and no-one seems to know why.

No problems here. A little under .25" clearance to the tie-rod.

Did you have the LE extended tie-rod end (correct bump steer on lowered 93 LE)? I could see that making it worse.

I have the same issue on my 96. I'm swapping in NB knuckles to see if I can fix it that way. Seems like the NBs aren't having any clearance issues.

Not happy with the rears at the moment. These are base calipers spaced out to Sport dimensions using the MTuned bracket that 949 carries. Rotor is a two-piece DBA setup that Goodwin carries, and has same dimensions as Sport. It weighs the same as the non-Sport one-piece, so I suspect it is about 2 lbs lighter per side than the Sport one-piece.

The part I am unhappy with is the dangling of the parking brake. These brackets rotate the caliper CCW abou 15 degrees and the ebrake gets pointed down quite a bit. In fact, the instructions say to loosen the chassis mount for the cable when installing. I had to leave it unattached.

I haven't done the other side yet, as I am contemplating the situation. If I bend the bracket that attaches the cable to the caliper, it distorts the pull angle. Could probably get away with a little, but it needs a fair bit.

I have to believe others have solved this. In addition, the V4 Goodwin kits have similar rear brackets, so I'd expect those folks to also have dealt with this.

Anybody?

As usual I have done nothing about it, few things stand up enough on track to catch them. 3-4 years running like this so far (I don't remember when i changed rotor size in the rear).

But as everything can be a bit different, are your cables hanging below the lowest point?

I would just buy the FM LBBK for the rear (powerlite calipers modded to have e-brake) if you want to drop more weight, just get their sport kit and it'll work with the sport rotors.

Already considered and rejected in the planning stage.

Not the piston bore ratio I want. If I was to go that route, I'd just swap to larger-bore OE rear sport calipers and ditch the brackets.

Further, the FM ebrake is very light duty. I use my ebrake heavily when towing. Stabilizes the car quite well. I can always tell when I have forgotten to put it on.

Interesting on the towing part. Yeah their ebrake is very light duty and thats really the only solution unfortunately. I've tried to come up with a way to improve on it and nothing else fits.

You dont like piston ratio between the front and back even with the 11.75 fronts? Math I did makes it seem better than the stock caliper because you wont need to use as skewed of a pad mu to get the right brake balance when trail braking. The sport would have been my caliper pick if the FM LBBK didnt exist if the sport caliper had the same brake pad support as the normal caliper.

At the moment, yes. But the car is still on stock suspension and that pic was taken at full droop. Doing some rough measurements this am, it appears that I'll be knocking a good 3" off the droop travel when the XIDA's go on, so the cable will likely tuck up a lot better.

I think I will go ahead and do the other side...and hope.

I'm on stock 97 tie rod ends. Make sure that .25 clearance doesn't get worse as the suspension compresses- that's what got me... Looked fine up in the air, scraped up the rotors under cornering and bumps.

Let me know if you figure anything out (without using the grinder )

An alternate solution is using OEM Sport carriers with either sport calipers (1.375" piston area) or 94-00 calipers (1.25" piston area). I believe this is what we did on the few cars we ran Sport rear rotors on. In restrospect, that might have been a simpler solution for you.

Just researched this via parts fiche. Looks like the knuckles are indeed different between Sport and non-Sport. (NO75-26-28X/29X vs NA75-26-28X/29X)

So you are saying that either caliper will fit on either knuckle...and that the knuckle is the determining factor on the rotor spacing?

Wow I never noticed that. BUT thats the part numbers for the assembiles. If you look further down to just the hub there's only a different part number for with or without abs. So the difference is almost certainly just the diameter of the brake shield.

The carriers and calipers are interchangeable. Pad is determined by the carrier used, not the caliper.

Sport pads if you put NA8 calipers on Sport carriers. M-Tuned adapters, NA8 or NA8 depending on carrier used.

The caliper carrier, or bracket if you will, is different between Sport and standard, but the lug spacing and offset are the same. The pin centers, diameter and offset on the two calipers are the same. Ergo, one can fit Sport carriers (brackets) with non Sport calipers onto non Sport knuckles.

We have tried a bunch of different combos. Running 11.75's up front with Sport rear rotors and minimal aero, NA8 calipers. With huge downforce, porky car (V8), or 275's, the bigger piston Sport caliper starts to give better balance.

No idea why the Sport knuckle has a different P/N than the base. There was only what, one year of overlap AFAIK.

Sport calipers can be made to work on non sport brackets as well. Just a little grinding on the backing plate of the pad to clearance the caliper. It is better to use the larger rotor, but it gives more options.

I did this mod as I run RPF1's, and needed more rear bias.

^Same here.
I'm running the rear sport caliper on the non-sport carrier. Didn't like the stock bias in the rain, so I upped the rear pistons. Stops faster in the dry (I measured back to back) and wet, and is much safer.
I still have the carriers for the sport rotors, should I choose to go that path in the future, but currently, it's nicely balanced, and does the job.

Quick release passenger seat mount is now complete. Slider is gone so seat sits 1.5" lower. Rear hooks on pins, front gets bolted. Might change that to studs. Goes in/out fast.
