20 vs 19 ultimate performance?
20 vs 19 ultimate performance?
Ok, looking for knowledgeable input. Setting up the rcf for primarily track duty, some street, but mainly autocross leading to the bigger road courses. Penske coilovers with minimal drop are on order. Pilot sport cup 2’s will be the regular tire.
Looking hard at the Vossen wheels. Love simple, strong and light. It seems she keeps going to 5,6 and 7 spoke (it’s her car!).
Whatare your thoughts Andy input on a 19 vs 20 inch wheel? While looks count, I’d put a brick on her if it improved the performance!
again, looking for strong, light, race capable wheels. 𝙈𝙖𝙭𝙞𝙢𝙪𝙢 performance is what I’m lookin for.
thank you for all replies

For any given tread width, the 19 inch would be better in every way than 20s in performance/handling. More sidewall means tire "bites" in the corner harder, smaller overall rotational radius and the 20 inch will also raise the roll-center of the car making the car roll along a higher pivot point in corners.
19 inch is the minimum we can do on the RCF due to brake clearance and that is what the best circumference is for performance.

No, I think 18s will not work with spacers because the brakes are 15 inches and then the callipers above the brakes also add a few more inches. It might fit, but it will definitely be a tight fit

Yeah, certain designs from what I believe, can make the 18 inch wheel clear the brakes, but there are not many. Design of the rim, I believe has a lot to do with it.
