Roger, 150lbs overweight in S isn't too bad. And, by your own admission you have "reasonably" light components. You might need to get out and search for that last 150 lbs and it might be hard. I'd be trying to get 110 lbs or so and keep the car 30-40 lbs over to account for variances in scales at tracks.

There is/was a well built ITS Prelude like yours on another race forum that is at weigh if I recall. Extremely well built car. It also makes in excess of 177hp at the wheel too, and is quite competitive in ITS. Based on that info I doubt it'll be moved it ITA.

I race an ITS Mustang. I'm hoping to get within 250 lbs of my weight minimum AFTER this season's round of weight improvement and $$$ spending.
