250whp at 205 tires??? will I die?
I was planning on running 99 wheels for both the street and r-comps track with 205's because I'm poor. I can get a set of nickel 6ul's with rs2's at the wear bar for $600. I don't really want to spend the money.
With that said, r-comps are only $130 for the 225's, but that might be too much traction for my 450/375 springs with bilstein HD's on the track. Any thoughts?
Also, are 205 street tires going to be scary in comparison to 225's? I only know of RS2's in that size and don't want to pay that much for street rubber.
Is passing on these for the track going to be a mistake? I love the idea of running crappy wheels I don't have to worry about bending or getting stolen, but I may wish I had more rubber on the track.

t3/t4 about 12-14psi here. 205 kuhmo cheapies, i have zero traction problems as long as i ease into gears. 1st gear is planted, but it will spin like crazy if hitting gears to hard, and if i use flatshift.

205/50/15 rt615's at 7psi ona gt2871 with a front RB nb hollow 1 1/8 sway, solid endlinks and 450/350 springs gives me some issues in the corners..
Exiting corners wot is difficult without alittle spinning, and that is with a high preload rx7 clutch lsd, I believe a 225 would preform miracles for my exit speed.(Not to mention braking distances) And I should add corners are a second gear affair at my track, so consider that aswell(no high speed sweepers here)
I would higly recommend stiffer fronts, like a 550 or better, 350 in the rear I feel is great for a street/track set-up but the 450 fronts aren't what I'd call a track spring rate.
Wide wheels and tires are a no brainer no matter your budget as long as your class allows it.
205's just don't give you quite enough in the tighter corners imo, an r-compound might help enough but I'd spring for the 6ul's with some big tires.

im running 195s with stock suspention. Going straight is no problem through all the gears, turning I can break free fairly easy, espically with a open diff.
Rain, 1st, 2ed, 3rd, and 4th gear are all scary... haha

I'm in money saving mode to buy a house right now, so I really don't want to spend the cash. **** **** ***.
Yeah, I'm going to chill on this. I am not required to have the fastest miata around, just required to have fun when I go out.

Street tires are scary as **** on track, period. My car was a handful on track with the 225/45 R-S2s; at only 200whp I had several solid 3rd gear slides and one very scary 4th gear 100mph+ slide. The 225 R-comps make my car easy and fun to drive again; the street tires made me afraid of the throttle.
BTW, Toyo is going to release their new R1-R street tire in 225/45, so there will be 2 options for streets in that size. Apparently the R1-R runs wide as **** for its side (apparently someone at Toyo thinks a "205/50" means it needs a 221mm case width) and they are sticky as hell (durometer readings on par with RA-1s). I'll probably throw some 225/45 R-comps on 15x9s and run those for the streets on my 8s.

If your just going to have fun and not be the fastest, then your 205's will be fine. I still recommend stiffer front springs, even some no name ebay stiff springs would be better (mine are "dropzone" lol and cost 60bux for all four with sleeves)

I just read and they have a 140-treadwear rating, heat range of 160-220, so basically it looks like I may have found my track tire after I burn up these 205 nt-01's.
lol

225/45/15 R1R will be awesome, but it will wear faster then a ... <insert funny ending here>
When my RS2's wear out the miata will probably be retired from DD duty and on go the 235 R888's.
