Yes. I do it every few years. I've tried RAGG TOPP and the factory spray. I prefer the results of the factory spray. I buy three cans and put on 2-3 coats. The only hassle is you need to mask off the car's paint and rear window.

Cool, thanks!

Mr.Alex

I'l keep the channel lock pliers in mind, although the clearance between the ****er and the rod that goes to the rear is tight to grab on to. I'l try to use another jack from the middle, but when I used my low rise rack from the outside of the car it literally lifted the car up off the jackstands instead of it popping in.



Second quesiton; I have to replace my wheel carrier/upright in the near future. I'm looking through the parts diagram and there seem to be quite a few things to replace. I'm certainly replacing the bearing, but what about some of the other things, like the lock nut [~35$], spindle washer [~170$], wheel hub flange[~20$], etc.

The lock nut is use once. Since there is no outer lock nut (like the RS has), I wouldn't skimp there and just get a new oem one. Last thing you need is that nut backing out....

Hi all

Does anyone know the part number for the headlight adjusting screws. Mine seem bent, not sure how but they are.

Rocket Rob

The part number is 991-631-132-00 (M4 x 9)

Goughary

Are the part numbers the same for front calipers between the c4 and the c2? I'm thinking to pick up a used set of C4 front calipers as a quick fix for the spring...

My understanding is the only difference in calipers is on the rears. But are the piston sizes on the c2 front calipers the same as c4 ?

cobalt

Yes all the fronts are identical in size both use a 40/36 piston and same sized pad the only differences were the rears on the 90-91 C2's used a two piston 44mm per side vs a 4 piston 30/28 which was fitted to all the C4's and the 92-94 C2's.

The caliper design changed in 92 it went from having raised letters vs painted letters that said Porsche. I have a reconditioned and painted set of older style raised letter fronts if you are interested PM me.

Mr.Alex

Going to sound like beating a dead horse here, but placing order for all parts for wheel carrier swap, and am really curious if the spindle washer/ thrust washer/ shake proof washer is re-usable. Its the priciest part on the list and I can't find anything about it in the workshop manuals, nor any older threads.

Its the star shaped washer on top of the hub in this pic.

Or part #14 here:

I might be mistaken but part number 14 is the ABS toothed ring gear for the speed sensor. I am assuming this is the piece in the upper left hand corner of the photo you are asking about?

Not sure why it would need replacing but if it does I have some used parts floating around.

Mr.Alex

Well thats good to hear, nothing wrong with mine, just wondering if it was a 'replace' part like so many of the other parts in the workshop manual.

ThomasC2

Part 14 isn't something you replace. Just put it back! I did replace the bolt 15 though, just because it felt like a good thing after 22 years, but you don't have to. The nut 16 must always be replaced though. Good luck!

JasonAndreas

The only time you should need to replace the tensioning ring is when you are replacing the wheel hub with a newer version. The newer version requires a smaller diameter spring washer that centers it on the hub and not on the bearing ring. Then you will also need to update the tensioning ring. Here's the TSB.

cobalt

Does anyone know why they call it a tensioning ring?

Star thanks for this. I'm of to shop.
