Caliper to wheel clearance is part of the reason why a number of R35's run 19 inch track wheels instead of 18 inch track wheels.

There is a new article on our website here which explores the 19 inch track wheels options for R35's, and discusses caliper clearance, tyre choice, lateral stiffness of wheels, cooling considerations etc in detail ...

i agree greater clearance is better, 3mm might be recommended (sounds like a magic number someone plucked out of their clacker to be frank) but anyway running 18" rims with less clearance than that - whilst not ideal - does actually work fine, speaking from experience and watching several others.

"Brembo recommends a minimum clearance of 3mm between the caliper and the wheel spoke or rim."

Brembo are one of the most experienced specialist motorsport brake manufacturers on the planet, so if they recommend a particular minimum clearance, that minimum clearance will have been specifically chosen by Brembo for engineering reasons.

http://en.wikipedia.org/wiki/Brembo reads ...

"Brembo brakes are standard equipment on supercar marques such as Aston Martin, Audi, Ferrari, Lamborghini, Maserati, Mercedes-Benz, Pagani and Porsche cars, and on some high-end American sportcars such as the Ford GT, Chevrolet Corvette, Cadillac CTS-V, and the Dodge Viper, and even factory performance coupes such as the Chevrolet Cobalt SS Turbo and the Hyundai Genesis Coupe Track Edition. Other marques that have Brembo brakes (either standard or as an option) include Acura, Alfa Romeo, Buick, BMW, Chrysler, Fiat, Hyundai , Jaguar, Land Rover, Lexus, Mitsubishi, Nissan, Peugeot, Infiniti, Pontiac, Renault, SEAT, Subaru, Volkswagen and Volvo.

The following motorcycle manufacturers use Brembo brake systems: Aprilia, Bimota, BMW, Ducati, Harley-Davidson, Husqvarna, IMZ-Ural, KTM, Moto Guzzi, MV Agusta and Voxan ...

Brembo brakes are also used by a variety of Formula One teams including Ferrari, and the majority of MotoGP teams use Brembo brakes."

Brembo was established in 1961, so when Brembo make statements on minimum clearances, they are speaking as a specialist brake manufacturer that has been operating for 49 years and they are speaking from experience at the very highest levels of motorsport.

Thanks guys,

leaving wheels for a while yet I suspect some moreoptions will become available.

Do however really like the look of the Volk TE37 G2 wheel in diamond black. Not sure what sizes they come in though.

Martin from Willalls tells me the standard 18' TE 37's only have 1mm clearance from calipers !

It the same with the replica rotas too, there's bugger all in it. It's not ideal, but it will work. 3mm is a magic number which cannot apply to all wheels, rotors, how it's vented (have you seen how the brembo rotors are vented? - get some ap's - they are better), pads used, tyres, which track, how you drive, etc etc etc. All we can tell you is it works - in the real world on our cars - because we have done it.

You can increase the clearance somewhat by using spacers (for another mm or two) however i am sure there are experts that will tell you spacers are evil, so i will not bother. If you want to run 18's with the maximum clearance you can get (a lot more than the te's) there is another option. It's relatively cheap, but they are a quality jap rim. R35 owners can send me a PM and i will share the info.

There is a thread about Enkei 18" GTC-01 wheels on NAGTROC which was started back in March 2009 ...

http://www.nagtroc.org/forums/index.php?showtopic=29400

We are currently checking with Enkei to get exact data from Enkei on how much caliper clearance the Enkei 18" GTC-01 wheels have if used on an R35.

Hi Jeremy,

The Volk Racing VR.G2 wheels are made in 16's, 17's, 18's, 19's and 20's in a range of widths and offsets.

See the photos of this Australian R35 ...

There is a closeup photo showing the wheels on that car in it's photo gallery.

gtc give good clearance, i've run them for a dozen track days but they have offset issues. there are other options.
