Has anyone tried a Narrow Superlite Radial?

I'm in desperate need of something more than a Dynapro 11.75 but am not willing to give up street 15x8 wheels, and would rather not get rid of my 15x9 6UL gen 4s. From the clearance diagrams, the clearance looks close to a 4 piston dynapro lug assuming 11.75x0.81 on both....

Forged Narrow Superlite Radial


Yes the caliper is more expensive than the Superlite 4 piston lug and with narrower pads (16mm vs 20mm), but if it means I can still have a streetable wheel and tyre combination, then it is worth it to me. It's also available in the right piston sizes. I'd rather change to a Stoptech or AP Racing caliper but I can't see any that offer a pad as large as the 7416 with as good wheel clearances on a 11.75x0.81 rotor and correct piston sizes.

Has anyone tried this?

6 pistons? https://www.good-win-racing.com/Mazd...t/61-0305.html
Or the radial-mount 4 piston dynapro is a step up from the lug-mount you have shown, though not sure by how much.

The 6 piston dynapro does appear a fair bit beefier, I'm not sure why it's not more widely used.

But I would like a bigger improvement in caliper stiffness so would like a Superlite class or similar.

I have a 12.19" setup we put together but didn't list it online yet. I will find my clearance notes for the wheels. I also have the FSLI calipers that i bought to put a kit together and test. if you can wait a handful of weeks, I can get something together for you.

Thanks, that's really helpful. I'm guessing that's the full width lug mount superlite? That won't be anywhere near fitting a 6UL 15x9 with a 12.19" rotor. The narrow superlite radial is almost 10mm narrower,

I found this CAD that appears to be an FNSL4R online, but I'm not fully confident in it..... I will give it a print and test fit though.

I sent you a private message. I do have all of the stuff to get this together and fit tested.

The FSLI is better than the radial for clearance.
