Default Brake Caliper Refinish DIY with VHT Paint & Caliper Upgrade on 997.2 C2 Base

I have a base 997.2 C2 which has the closed calipers, and had been wanting to change them to the open design of the C2S calipers. Particularly because of the ease of changing pads. I've also wanted some color to contrast against my black car and wheels.

A while back I bought a set of low mileage but shipping damaged 997.1 C2S calipers. See pics below.
The 997.1 C2S calipers are a direct fit onto the 997.2 C2 and C2S.

EDIT - FOR CLARIFICATION: I also added the "S" Rotors at the same time as they are a different from the NON-"S", and painted the top hats.
See the parts list I assembled at the end of this thread.













A couple of weeks back I cleaned up the calipers with a Dremel and sandpaper to sort out all the scratches and chips in the paint.

I used the following wing nut connectors to seal the caliper lines and bleed nipples.

I then used the VHT Caliper Cleaner to thoroughly clean and degrease the parts.



I then masked the areas that I didn't want paint on.
After a final wipe down with 70% isopropyl alcohol and allowing for thorough drying, I painted with VHT Red Caliper Paint.

Applied 2 light coats followed by 1 medium wet coat with 10 mins dry time between each coat.




The paint lays down really well from these cans. 2 Cans was perfect for covering all 4 calipers.
I highly recommend using the 3M spray grips:
http://www.amazon.com/3M-90201-Paint-Defender-Trigger/dp/B00BHH1QT4 http://www.amazon.com/3M-90201-Paint-Defender-Trigger/dp/B00BHH1QT4




before this project I bought a cheap countertop oven and used this to bake the calipers for 1 hour at 200 deg F.













The paint finish really had excellent gloss and very good smooth finish after baking.
the following weekend a wet sanded a couple of minor areas that were not 100% and the gave the whole caliper a quick once over its BlackFire SRC compound.

I then applied caliper decals sourced on eBay.
I decided not to clear coat because the finish was so good and glossy as is. Also I figured it would be easy to replace the decals if they ever deteriorated.

I am really happy wth the end result. The color match is perfect for Porsche red.

The only mistake I made was to not lay down a sufficiently wet 2nd and 3rd coat on the inside of the calipers. this resulted in a more matt / slightly rough finish on the insides of the calipers around the pistons, which is not really an issue as it is not visible, but as it s not super smooth it will collect more dirt. (lesson learnt)

Ive installed the calipers and will take more pics on the vehicle once it stops raining. Overall I am extremely happy with the result. I'd caution not to undertake this task if you're not willing to put many hours into the prep, which is by far the hardest part. the painting is easy

Also my thanks to Rennlist member Kaylan, for some helpful advice and his posts here:
https://rennlist.com/forums/996-foru...l#post12035494

and to Rennlist member Marc Shaw, for confirming his findings on baking the calipers here:
https://rennlist.com/forums/964-foru...l-cookies.html

As well as Pedro'sGarage for the great idea of using electrical wing nuts to seal the caliper openings.

I also did the Rotor Top Hats at the same time.
Sanded down and cleaned off the factory coating and then sprayed with VHT Satin Black.
1 light coat followed by 2 medium wet coats, and then baked at 300 deg F.

Wow... I never thought of baking paint job with a cheap counter top oven. Great idea!

Well done. They turn out great.

wow, looks really good! I did this on on old 350Z in 2003, but I never baked them, where did you learn that trick? The gloss looks great and they look like the thick coat from the factory, which is very difficult to do, without powder coating.

Good job!

I would recommend to anyone else who tackles this job to place the decals UNDER the clear coating, this will help protect them form the obvious. Otherwise the baking does help in the curing state, however we will typically allow the calipers to cure on their own BEFORE baking, I unfortunately cannot elaborate on the time and temperature we use during our hard-baking process as this information is considered proprietor.

The the decals in these photos were placed under the clear coating for reference.

I'd say after looking at these "professional" jobs, it confirms what a good job the OP did.

btw, don't worry about the decals not being UNDER any clear coat. I have done it over the paint in the past and even tracked that car and drove it very very hard and over 5 years and 60k miles the decals never changed color, cracked or were damaged in any way. As long as its a good quality/proper vinyl, you are fine. And heaven forbid, something did happen to them, its an extremely easy and cheap "fix".

Looking good!

Here's a set I did with VHT red caliper paint, black Porsche decals & clear. Not bad for paint!

Nice, nice write up and detail. They turned out really excellent. Those surfaces take some abuse for sure, and I'm guess the baking greatly increased the durability.

Thanks & yes I was really impressed by the level of gloss and the overall finish. I've done a fair bit of painting and VHT definitely is good for this application.

Thanks. I even bought the clear coat for the job, but after seeing a number of people on the forum had success without putting clear over the decals (over several years of use), I decided to do the same. It also makes touching up and re-coating easier in future if needed.

Thanks - the VHT instructions recommend the baking specifically to cure and ensure resistance to brake fluid, but I think it also gives the paint better overall strength.They do say that the paint will cure from use of the calipers (normal heat cycles), but that it won't be chemical resistant until properly cured.

Great write up and better results. I have the factory red calipers. Ive never owned a car with painted calipers and I kinds of like them!

BUTZI - that looks really good also. Ironically I also bought black decals, but when I couldn't find any good pics of Red Porsche Calipers with Black decals, I decided to stick with the traditional white. Now I know that black also looks really good.
