Was searching for pictures of fitted Superlite kit (in anticapation) and came across this thread I had forgotten.....Very excited, waiting for kit to arrive.
Hopefully be able to answer my own question within the next 5 weeks (if engine rebuild goes according to plan!).
First race of the season on the 2nd September then the first race of the new Improved Production series with 2 x 30 minute races the weekend after....should have a good idea of the difference by then if everythng else holds together.
To be fair Im hoping to have the upgrade from 1600 to Sport rear calipers fitted by then too so may not be a direct comaprison.
We fitted the new Superlight calipers and the sport rears.
Removed Booster and used the standard MC but changed the pedal leverage ratio.
Apart from a strange need to pump the pedal hard for 3-5 times after left hand corners the brakes felt perfect. Very similar to the 11.75" dynapro setup but with considerably less heat.
Running wirth 3 season old NT01's against semi slick Hankook and other top level tyres, on low boost while checking diff cooler and pump, engine oil cooler and watching/logging oil pressures (we run a big end and ruined a crank last time from possible oil surge) we came 2nd in the first race, and would have been 2nd in the 2nd race but for a failed tyre valve stem causing a deflation and eventualyl a flat in the front left.
Annoying as the Orange TPMS system told what me was going on but the TPMS valve stem coming loose was the bloody cause!!!
Also annoyingly the top 4 cars were running illegal aero which we had removed to be "within the rules" only to find out the rules are "flexible" this first season to get numbers up....so moving to 18psi from 12 and refitting our aero, we should be in good shape to be at least fully competitive.

Another data point for wheel fitment. These stock 16's from my '04 do NOT fit. Spokes hit caliper.
May have more data points later. My shop talked about test fitting all the wheels they have around when I take the car in for an alignment. They are interested in these for their v8 customers.
Depending on offset they may fit. The lower the offset, the better your chances. The tight spot is the drop center of the wheel, so reducing offset (shifting the wheel outward) gains you clearance there. The old 15x9 +12 Exocet 6UL fits, for instance, but the normal +36 version does not.
Sorry for the huge necro thread revive, but looking for input on anyone still running this kit. I picked up the kit used and test fit the other night and was really surprised when my 15x8 Storm S1s seemed to clear fine no spacers. (Previous posts in here showed a spacer needed with 15x9 Storms) Only thing I could potentially see was having some interference depending on where wheel weights get placed but mine didn't hit.
I have 15x9 dekagrams for the track that clear by even more but now I'm considering keeping my storms for a street set, or wondering if I somehow have something wrong. Not sure how I could possible have messed anything up haha. One thing I didn't expect was the trackspeed rotor hats are thicker than OEM rotors and act like a small spacer so I want to wait for my extended studs anyways to get some turns back.
Another thread necro but just to update anyone who’s tracking what wheels this kit will work with, these 15x8 et36 fit over the brakes with no spacer required:
The narrower 0.810" rotor makes a lot of difference. Since the gap between the tie rod and the rotor inner face is pretty much already at minimum even with the stock braking system, every bit of rotor width pushes everything out to match. It's almost 1/2" less overall caliper protrusion, and since pretty much any performance wheel is targetting that 25-35mm offset, it makes sense that the same model of wheels that clear the 1.25" brake setups in15x9 clear the 0.81" brakes when the wheels are 15x8+25.
If getting a narrower wheel with a street-ish tire around your BBK is a concern, and you can design your own parts, the Superlite Narrow calipers use a 7416 pad instead of a 7420. The last two digits denote thickness, so that's another 4mm you can get. The narrower caliper is commonly used on Corvettes so it's not like you're neutering your pad options or pad life.
Or just run 16" wheels on the street. It's not 2015 anymore and the 2015/50R15 tire market isn't supporting a whole lot of options for a true street summer performance tire. Set your car up for the track and run some quick removal bump stop packers if you're getting any rubbing over bumps with the larger 16" wheels and tires.
Yeah, once I thought about it more it makes sense why the narrower rotor helps clearance so much. Also can confirm they clear factory NB2 sport 16" wheels, which I use for winter storage so that was nice!
