Flow one F2 race spec wheels. At 19 and some change lbs in 18x9 et45. Perfect fitment on stock height. View attachment 245396View attachment 245397

Same brand wheels in their 19” flavor in silver. Those mounted with Bridgestone RE71r’s shaved off 8 pounds a corner as compared to the stock 19” Pretoria’s with stock size Yokohama tires

I could be remembering it wrong, but I’m pretty sure it was 8 pounds a corner. One set is my daily, one set is for autocross and the track.

Stock Prets are ~21.5lbs. The F5 are ~20.5lbs. The tires on the Prets would have had to have been 31lbs each to save 8lbs a corner, nothing in the OE size comes anywhere close to that (most at 23-24lbs for 235/35R19). Most likely the weight savings was close to net zero.

Do those 235/40R19 rub at all? That is good bit taller tire than the OE size.

You are right. I’m wrong. Not sure why I was remembering 8 pounds a corner. I went out and weighed them:

So, about 5 pounds total. I was way off. No excuses.

The race wheels do rub a little if I hit a hard bump in comfort mode. I plan on going to a 255/30 the next time I need tires.

No worries. 8 lbs a corner would be awesome, just not realistic for us R owners that had Pretoria’s. Now all the other guys, they get to save some serious weight.

Looking good and make a nice change from seeing the more usual 18 and mostly OTT 19" options.

Given that my modest flow-formed 7J x 16" + 205/55 outfit tip the scales at 15.15 Kg/33 lb each, I was a tad surprised
to see that your 'sensible' 17" size forged wheel + tyre combo still weighed-in at 32% heavier at 20 Kg/44 lb
- then I noticed those alloy beasts are a full-on 9" wide with 255 tyres to suit...😳
