My plan
So I'm currently building a 400 whp miata and as of wheel/tire selection I'm not too satisfied. I know the current widest tire I can run is a 225 on a 15x9 (I could do 245 on 16's but the tire selectino is not there) So my plan was to get some 17x9 or 17x9.5 enkei rpf1's with a 245, 255 or maybe 275 tire all around, get a 5 lug spacer/adapter, some fenders and have my traction or at least a little more than a 225 can offer. I nkow this will throw off my speedo, id there any easy way I can compensate for this? Does this sound retarted? lol Either way it will be different and I will have good traction. share your thoughts....

because they make the power alot faster.
and if you sold a car with r specs, the drivers would be pissed when they brought their car in for its first service where they needed to spend another 1500$ in tire.

You could also consider how the torque comes on in your car, and try to optimize that so that it is more easily controllable in the first place. A flattish torque curve with a declining slope with RPMs provides passive traction control FWIW. You could also think about tunable TC. Cars with very drivable natures frequently outperform somewhat higher dynoing cars with lesser drivability / throttle response.

Fenders, spacers, and 17" wheels are not worth the extra $$$ for limited width advantage.
With the weight disadvantage, you might as well make it a 350hp engine anyways.
Either:
A. Settle for low mileage on R-comps or,
B. Learn to control your right foot with street tires

If you can get into suspension part changes and altered pickup points, then you can adjust things like antisquat such that the rear briefly but usefully pushes down more on throttle down. Ala live axled muscle cars. When the Miata was designed the suspension did not need to accommodate high torque. It's a design issue too, not just rubber.
