15" wheel with Z32/bigger brakes... - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Does anyone have experience with Rota Grids and how well they typically clear bigger brakes? In my case we're running Z32 brakes all around (30mm aluminum in the front) on a 5 lug S13.

We're looking to throw some 15x8 et20 Rota Grids on our Lemons/Chump car for a number of positive reasons (1" lower, 225 on 8" instead of 7.5", shorter sidewall, higher (lower geared) effective final drive, 7lbs lighter per corner, cheaper tire, etc...). Currently running Z32 16x7.5's with 12mm spacers.

Here are the Grids we want to buy:

We know that Z32 brakes fit inside the ID of 15" wheels (people have run the stock S13 wheels with Z32's), just want to be able to run the the Grids without spacers since spacers are a value adder in Chump. By the looks of how the spoke juts out immediately on the Grid, and the offset, I'm thinking they'll work. Maybe someone has more experience on here, or could maybe recommend another 15"x8" 5x114.3 wheel (they don't seem to be very common). Just trying to avoid buying the set and then have to absorb the restocking fee if they don't work.

Thanks!

Debating on the Rota grid and Rota slipstream, any ideas on which is better suited to clear z32's?

Here's a pic of a stock s13 15" wheel over z32 calipers:

in case anyone cares here. Copy and paste from my thread over on nissanroadracing.com:

Ok, so they don't clear without a spacer...bummer. It's close. It will require a minimum of 5mm spacer based on visual inspection. Seems like if it were an 11.5-11.75" rotor to push the caliper out a bit further from the hub center they would work. They easily fit inside the barrel, which almost makes me want to consider the Defsport kit as a slight possibility to fit inside a 15" wheel. There's easily a 1/2" of space between the caliper and the ID of the wheel on inspection, but I still need to measure.

Anyway, here are some pics.

Inside the barrel. Plenty of space.

Spokes don't come out soon enough off hub to clear:

Here's with a 12mm spacer. Plenty of space
