Weight Report - 17x9 6UL and 245/40 Pilot Sport 4S

Tires & Wheels - MX-5 Miata Forum - forum.miata.net
Just installed a new wheel/tire setup on my son's new-to-him 2006, and compared the weight to what came off to what went on.

What came off was a set of Drag DR31's in 17x7 with Bridgestone Driveguard 205/45-17 runflats, that weighed in at 43 lbs. each.

What went on was a set of 6UL's in 17x9 with Michelin Pilot Sport 4S 245/40-17, that weighed in at 40.4 lbs. each.

That's a savings of 2.6 lbs. on each corner, or 10.4 lbs. total, of reduced unsprung weight, while increasing each wheel width by 2" and tire width by nearly 1.6", for nearly 6 1/2" of more rubber on the ground.

The car is still on the stock suspension and as of now does not appear to need a fender roll. I'm doing an alignment tomorrow and plan to install Ohlins coilovers in a month or two, so it's possible a fender roll may be necessary then.

I haven't driven it yet, by my son said it's a night and day difference in cornering. Also, we love how the car went from looking cute and sporty, to mean and aggressive with the new wheel/tire setup!
