I upgraded from Boxster S rotors to the Cayenne 330mm front rotors on the Lexus calipers....Zero fade no matter how I abuse them.

Well, there you have it. CANYONS! GT3 brakes are a minimum. I'm from Houston. Drive straight for 30 miles, turn right. You're there.

They would have worked better for me since I have the 350mm rotors.

Go back, pick up vented nose panel, get some tacos... then you are there!

The 330mm and 350mm Cayenne rotors are an excellent choice due to much lower cost. Plus they're not drilled so they'll stand up to track use. You'll have to account for the slightly different offset (1-2mm) from 996 or 997 rotors.

The big drawback to any of these large rotor setups is the weight - typically 23-27 lbs per rotor.

My pictures show the 330mm Ceyenne rotor, and I am thinking of picking up a 350 for mockup and to verify this setup with a 350 will fit under a 17 inch wheel...

as the 18s in my picture are the only set of 18s i own, but I have 3 sets of 17s...

The LS430 calipers now have varous pads from Carbotec, great bite and wear and no dust.

How easy was it to deal with the brake lines?

It looks like if you're a fan of bling/big bits, you should put bigger brakes on no matter what kind of use is intended. The canyons I would consider a track. I'd imagine there are canyon roads that have higher braking requirements than many tracks, but not around Atlanta or Indianapolis. We have creek bottoms....

I went through this fire drill last year. Stock brakes were retained and I don't regret it.

Well put. BTW nice gloss and mirror upgrade.....

18Z vs M030

Not so much a bling thing, but I hate the look of my current brake set up. I could always go the drilled rotor look and a much better brake pad to improve things.

If you are getting smoke and fade something is wrong. Use Motul or SRF fluid,get some front ducting to them and an aggresive pad . I race with them and never have I seen them smoking.

It seems guys with the 86-88 non M030 have more choices in terms of rotor/caliper upgrades. Those 330-350 mm set up are from 86 spindles correct?

Anybody running larger than stock rotors on 88-89 turbo S and if you don't mind sharing your experience?

I run the stock brakes on my '86 951... but have big brakes on my wife's VW GTI (993TT rotors and Boxster calipers), and also had big brakes on one of my old Omni's.

Bling factor is cool (IMO my GTI looks pretty awesome with the giant rotors and yellow calipers) and the car definitely stops like an animal on the street and on the autocross course. Seems to take a lot less pedal effort to get the car whoa'd down.

For track work, with the wrong pads (Hawk HP-S), they were awful... and at one event I was consistently out-braked by another guy (also in a GTI) running all stock hardware (calipers and rotors) but a racing pad.

My Omni, I wasn't really fast enough to run into braking issues with either the big brakes or the stockers when on the track. But street performance was awesome. Back then I also paid no attention to pad compounds, and ran whatever the guys at NAPA sold me.

So if you're comparing crap pad to crap pad, I think big brakes make a pretty awesome performance difference. But if you run a GOOD pad on the stock hardware, your gains will be limited.

But I also "get" the desire to improve the looks. Guilty of it too. If it didn't mean not being able to run my stock 16" phone dials I'd probably have a set of Big Blacks or Big Reds mounted up on my 951 already.
