I weighed both cars (my LS1 FD base model and a friends 93 R1) over the weekend at our autocross event at giants stadium. Both cars had spare removed. Both had almost full tanks of gas but my car has a reduced capacity tank which holds 5 gallons less. Both had stock 16 x 8 rims but i had 245-45-16's Yok AO32R's and rotary had 265-45-16 Kumho ecsta v700's. My car is missing AC, PS and ABS. My battery is in bin on passenger side whereas stock RX7 has battery in original position up front. His car is set up for SCCA SS class so its mostly stock. Bottom line is mine weighed about 15 lbs more but had a better weight distribution, no doubt due to the deletion of ABS, PS and AC and relocating battery:



--------------LS1 ------- Rotary

Left Front: 684 ------- 718

Right Front: 695 ------- 718

Total Front: 1379 ------- 1436



Left Rear: 705 ------- 660

Right Rear: 645 ------- 618

Total Rear: 1350 ------- 1278

TOTAL: 2729 ------- 2714

% over Front: .505 ------- .530

% over Rear: .495 ------- .470



the owner of the stock RX7 was my passenger on the last run; listen to his comments at the very end:
