Haven't needed replacement pads yet, so will cross that bridge when I come to it.

I started out with 4 cylinders, but it was way more difficult that way. With 2 cylinders, I know what the level is when scale. With 4, whenever I would change one all 4 would change, and I'd have to figure out what the new equal amount should be. Plus more tubes to trip over and fluid to fill. It was just a mess.

With the new system, I just leave one on the highest, and then compare, one at a time, each scale to that. Quick, minimal fuss, easy to determine if level, less stuff to store.

... when we move, I'm going to use them to level my new 4 post lift and then probably get rid of them. Once I know the lift is level, they are no longer useful.

gotcha, that makes sense. sometimes simple is best.

Interesting - I run 17x9.5 et35 all the time and have been thinking of a BBK upgrade soon, but I hate to buy something and have to just hope that it fits. I thought PFC made a BBK for fitting in a 17 but bimmerworld shows it as not available. Haven't done any more research though...

On the garage I'd only offer the standard advice - you can't have too much space, power or light. On light I did ok in our build, but I do wish I'd added more outlets. I did run 220v to two places, so that should cover me for any future lifts, compressors, or EVs. And like I mentioned before, the space where I'd put a lift is 8 inches of 4000 psi reinforced concrete. I'll have to post up some pics in my journal thread.

Well, if you hold off on brakes till the 17x9.5 ET35s ARC-8s arrive, I can tell you if they'll clear the 996 brakes. I also hate to buy with the hope that it'll fit, but I couldn't the answer find the answer anywhere and Apex said I could return them if they don't.

I'll be running 220v for sure-- Lift, air compressor, and realistically EVs are going to take over while I live in this house.

I'm about to put porsche brakes on, and couldn't be bothered with fiddling with the logo/repaint either! Did you get track pads sorted out through FCP? They seem to be out of stock of the good stuff for 6 months or so. My last conversation with a rep was that DS11.1's were backordered from the factory, not that they weren't going to carry them any longer.

Great idea on the vynil floor tiles, I'm going to try that out! Do you level left right/ front back/cross? Could you use 4 cylinders and not have to level the pads multiple times?

Ha. The stickers have double purpose-- hide the Porsche logo and tell me the caliper temperatures :P

I have two graduated cylinders, connected by a tube at the bottom with 1/2" rubber fish tank line. I put water with food coloring (to make it easier to see) in there, and fill them both ~3/4 full. I shim under till both cylinders read the same, at which point I know they're level. I try to figure out which scale is the highest, and then use all the others to compare to that (shimming the others up). Once everything is shimmed up, I zero the scales so they don't contribute to corner weights.

As shims, I use whatever the cheapest vinyl floor tiles I could find at Home Depot were (IIRC it was like $30 for 100 of them). They're ~1mm thick, so I can get reasonable leveling, and they're slippery-- so when I raise/lower the car, it doesn't get stuck high with the camber curve, and if I, say, adjust camber, I'm not fighting the friction of the tire on the scale-- the floor tiles just slide against each other.

The brembos fit under the specific 17 I run (not most 17s), as do the 996 calipers I’m now running. I have 17x9.5 et35s ordered that I’m REALLY hoping fit over the 996 brakes... I really dislike the et25 setup for track use.

I don’t really have any great garage ideas, beyond having it finally be large enough to not be annoyed. Open to suggestions!

Your Brembos fit under a 17 inch wheel right? I think I remember you running 17s on the track.

I'd also be interested in details on the new garage. We just moved into our new build in November. We expanded the garage in depth and width, put an extra high ceiling in the 3rd bay plus extra concrete. 99% sure a 4 post will go in late this year.

Solid feedback thanks. Any seat time on them yet? Thats where I'm anxious to know how they are

The brakes? Yes, I drove them all last year, street and track. That was the basis of the feedback above...

[Exclusivs]

I was driving on them last year. They're... 90% as good as the Brembo GT kit was. Better than stoptech or stock, and actually easier pad swaps than the brembos, but the pedal feedback isn't quite as good.

Also, they're a not insignificantly heavier setup.

But, FCP sells the wear items, sooo....

Slon wall didn't arrive in time for track season? Bummer, was looking forward to hearing your thoughts on it.

Nope... been stuck in customs for a while. Not Slonik’s fault, but still sad.

[heinzboehmer]

At this point I just need to finish a wiring harness I'm setting up, set the end links on the sways, and she's ready for the year

Nice updates Ian!

Looking forward to hearing your take on the retro-fit, VS real GT kit

Looking good, I like your brake caliper stickers!

Can you explain a bit more how you leveled your scales? Mainly, how did you shim to adjust the height and how did you set up the graduated cylinders?

Ha. The stickers have double purpose-- hide the Porsche logo and tell me the caliper temperatures :P

I have two graduated cylinders, connected by a tube at the bottom with 1/2" rubber fish tank line. I put water with food coloring (to make it easier to see) in there, and fill them both ~3/4 full.
