View Full Version : STL Weight

2490.75 lbs
or
2491
almost 100 lbs heavier than SM... yikes.

2430+2.5% = 2490.75, rounded to 2491.
Lot more ponies than Spec Miata, too, as well as bigger brakes, bigger tires, better trans/rear diffs, and rear wing, etc...
Ok wasn't sure what sticker to put on the car, thanks.

remember if you are running STL under SM prep you post the SM weight.

Ah, right; I didn't pick up on that. Dick's absolutely correct: if you keep it completely compliant to the SM specs - including restrictor plate - you're good to go at the SM weight. But remove that plate and now you've got to meet all STL specs, including weight and the 5" ride height. - GA
Oh great, then I just have to put one weight sticker on the car and that will work for SM and STL.
Thanks guys!!

If your car is ITA compliant , you can run at ITA # of 2380

'Zactly. But caveats with SM-into-ITA: SM-compliant diff mods, ride height, head mods, etc can make an SM non-compliant to ITA. Ensure the car is fully compliant to all ITA specs. - GA
