LansocK on here is running 19x10 et55 wheels with 295/30/19 tires. Zero clearance issues. So a 19/18 x 9.5 with a 50-60 offset will clear. The only issue may be caliper clearance.



Why would you not want a wider wheel & tire? A larger contact patch is always better.



I see you offer the R902 wheel in 19x9.5 wheels with a 56 offset in 5x120.65 bolt pattern for Corvettes. Is there anyway you can check to see if these clear our Brembo front caliper? I’ll buy them if you confirm this and make them in 5x120 bolt pattern instead of 5x120.65.

Are you able to design a 19x9.5 wheel with a 55 offset that clears the caliper? If so, I’ll buy em. You need 5 people to create this? I don’t see that being a problem at all.

For people that are concerned with scrub radius a 275/35/19 tire on a 19x9.5 wheel with a 55 offset will give you the same scrub radius as factory fk8 wheels & tires.

The NSX wheels with 245/35/19 tires that I keep seeing are close to stock will add 5mm positive scrub radius, so now you go from -2mm scrub radius to positive 3mm. Run a 255/35/19 tire on that NSX wheel and you’ll only gain 4mm scrub radius, so you end up at positive 2mm scrub radius.

The only two wheels, I know of, that are 19x9.5 with a 50 offset, confirmed to clear the brembo calipers are Volk Racing G25 and Advan Racing RSII wheels. These matched with 275/35/19 tires will add 7mm scrub radius so you have a 5mm positive scrub radius.



Seems like this guy would be 1 of the 5 needed to jump on a new wheel design.

This is the wheel that lead me to finding this thread. My only concern is the caliper clearance & and bolt pattern is 5x120.65 not our 5x120.
In terms of the Civic Type R, there is no problem doing a 5x120.65. If it was vice versa, 5x120 on a Corvette, there will be small strain on the studs but very minimal.

5x120.65 on a Type R is fine! There is no strain at all because the lug hole is just a tick bigger.

That's not entirely true. Because the hole is bigger, you will have more stress on the studs as the bolted joint won't be as stable. Really, you'd want to have wobble (PCD variation) lug nuts to correct for this. However, those seem awfully hard to find for our CTR's size. Are you able to provide them?

That’s not true, also the wheel will never be able to be centered on the hub. It may bolt up but isn’t ideal.

Will the R902 19x9.5 et56 wheels, designed for the corvette, clear the FK8 front brembo caliper? Forged wheels are made then the bolt pattern is drilled. Can you make the R902 wheels 19x9.5 et56, then just drill them In 5x120? If not, can I order them blank/undrilled? Again my main concern is caliper clearance. All other measurements are good.

Don’t mess with wobble lug nuts, there are many issues with them. I don’t even know why they designed wobble lug nuts. I looked into these and after reading up on them I decided against them.

Yes the R-902 19x9.5 et56 will clear the Factory Brembo's on the car. We can definitely make you a custom set of R-902 for your car with the exact 5x120 bolt circle in any solid finish you want. Build time would take 6-8 weeks.

@RSR Wheels is it possible to get the R902 18x10 ET 45 or even 50? without clearance issue?
