Progress Thread 12th Owner: My '93 Notchback Restoration & Performance Build

The email I just sent to Rock Auto. Un-believable!

I anxiously arrived home today hoping to finish the front rotor install on my car. I had already confirmed the front door arrival of my two "18A964A" rotors, but was shocked when I opened the box and saw two completely different rotors despite the packing list indicating two "18A964A" rotors. This is now the second time I've received a 14.5" rotor which coincidentally is useless to me as I can't even install it on my car's hub if I wanted to. I now have one correct 13" rotor and one 14.5" which I can't use. I'm requesting that you mail me a single 13" diameter rotor for a 2003 or 2004 Supercharged Cobra (part number 18A964A) as soon as possible (overnight would be preferred). This is my first interaction with Rock Auto and I spent more than $700. I understand mix ups, but why ANYONE would ship two completely different sized rotors with the same part number when they are visibly different from each other and having different weights is beyond me. I've attached photos to confirm my statements.

You don't want 96-04 spindles. Look for 94-95 on ebay. All the calipers and brackets , master can all be bought on rock auto. Axles can be bought separate too. E brake cables can be bought separate as well as all the brake line parts MM makes.

A little home work you can have all that stuff ordered from separate places.

5 Lug swap list



-94-95 spindles

-5 Lug axles ( i used moser foxbody length with 99-04 disc flange to keep fox track width)

-Master cyl ( see notes)

-Booster 93 cobra

-Cobra calipers(front)

-13inch rotors (front)

• 94-04 gt calipers (rear)
• 94-04 gt rotors (rear )
• 99-04 rear gt backing plates north race cars or cobra backing plates depending on what rotor you want to use

Maximum MOTORSPORTS parts

-Front brake line kit - MMBK8F

-Rear brake line kit - MMBK13R

-Adjustable Prop valve - BPV-1

-Stock prop valve disable plug - MM-2450-A



-93 cobra booster ( keeps threads the same for the hardware ) - a1 cardone - 5473155

-North racecars rear caliper brackets for use with sn95 gt calipers . Cobra and gt caliper is the same cobra would accept bigger rotor . You want the small rotor so you can get 15 inch wheel on at the track .

-Parking brake cable- center (50resto)- M2810a

Rear cables - (50resto) - LRS-2635D





"If you run the 13inch rotors with cobra calipers up front you will need 94-95 cobra master cyl -15/16th bore p/n- BMC-4 with MMBAK-8 adapters to tie into factory hard line " ( Max Motorsport part numbers )



If you run 99-04 gt dual piston front caliper so you can run a 15 inch wheel up front you would run 93 cobra master cyl ( 1inch bore) -BMC-2 with line adapter kit MMBAk-3 (max Motorsport part numbers )

I'm tracking and I appreciate it. I just spent three hours finishing the MC install and assemblying and finishing the pax side soft line connection AND connecting the driver side hard/soft connection. ALL that remains is installing the new/correct driver side rotor/caliper, torquing the caliper and bleeding the system. It should be on the road Tuesday at the latest.
