Upgrading my 'Daily Driver'

fireslayer · 07-27-2010, 05:24 PM

I finally have the car I've wanted as a daily driver and want to upgrade as parts need replacing with better and more performance oriented parts. My car is a 1988 Carrera coupe I want to replace the rotors and pads and was wondering what suggestions any of you may have. I live in Ottawa Ontario region drive about 45 minutes in and 45 mins out 4 days a week six months a year with 5 or 6 DE's when I get a chance. Looking for suggestions for rotors, slotted drilled or stock, pads etc? Any suggestions or opinions would be greatly appreciated. Also looking to fix or upgrade a/c unit, Thoughts?

Welcome to Pelican. It is customary to post pics of your 911 ASAP.

I did a search for brake upgrades but there are more than I can post here.

What I did find was a thread that has the basic upgrades for a Carrera. There is some discussion of brake/rotors/pads so it should help you out some.Performance Upgrades for an '87 Carrera?

In stock form, if they are in good condition, the Carrera brake system is awesome.

Thanks for your inputs. Like I said this is a daily driver for me to drive to work run errands and 5-6 DE's ( would like to try an autocross )etc. The reason for the upgrade is due to corrosion on the discs. Could go with stock discs, but thought if there are better discs for 15% $ than stock and are better I would splurge and make the jump. I plan on keeping this car for years and years to come. So a little upgrade every year to spread my budget and still allow me lots of seat time and no (stuck in the garage time) gives me something to look forward to (like Christmas morning as a kid). Will shoot some pictures this weekend and put them up as requested can't break Pelican traditions. Cheers

Rebuild it with stock rotors and pads but I think you want to be sure to get Porsche rotors if possible or Zimmer rotors.

Run a good performance brake fluid. I like Castor SFP as it is very care free and it worked better than the others for me but any of the popular race fluids will work if you bleed them just before going to the track and probably after the race weekend. I did not seem to ever have to bleed the SFP and never lost peddle but it is expensive.

Also, as you are using the car for commuting, run the stock style or other street approved sport pad on the street and change to a race pad for the track.

I tried running a dual use pad on a full weight 3.2 and it ruined two sets of rotors with uneven pad transfer. Made the car shake like an out of round disk after one intense DE session.

Note that with track usage you will probably fry your caliper piston dust seals so doing what you can to keep the brakes cool is worth considering.

Remove the disk backing plates. Also, it is good to get air to the brakes as much as possible. Some adapt 993 air deflectors, some get aftermarket ducting. It dose make a difference.

New stock rubber brake lines are a good idea. You can run SS brake lines but make sure they have a DOT approval and inspect them before and after track events.

Tires and corner balancing are factors.

Drivers style and abilities can have a significant impact on brake performance.
