Rota 16 x 8 Slipstreams

Post by 913kent »

I am investigating the purchase of four Rota 16 x 8 Slipstream wheels with a 34 mm offset for use on a 1995 NA Miata. These would be outfitted with aggressive 245/45/16 "summer" high performance street tires in all four corners. I do not expect to run track events, but could particiapate in autocross events. Mostly it will be a fun street car.
By my math, this offset will increase width by 1/2" over stock configuration and another 1 1/4 or 1 1/2" due to the increase in the width of the tires. I hope the 2" increase in overall width will provide a significant improvement in cornering and keep a good steering response. Will the fitment of the wheel/tire combination be a problem for my car outfitted with AGX shocks and FM springs under stock fenders? I expect the wheels to be approximately 15 lb each. Could you confirm this for me.

I did not enter the tire size correctly. It is a 225/45/16 not a 245/45/16. Please advise me if you think this is still too tall. Could you also advise me of the weight of the wheel.

Yep, that is still too tall. The size you want is either 225/40/16 or 245/35/16....lots of info already here in the forum on fitment for these sizes (use search function with these sizes to see pics, info, etc.)

Next question regarding tire fitment

Post by 913kent »

If I am looking to roll the fender lip to increase tire fitment clearance, is it necessary to use particular tools or machines to accomplish the fendor roll? Can this be done slowly by hand and appropriate tools?

Yes, the classic method is to use a wood baseball bat. That's no joke...do some searches on "fender roll" and you will find lots of websites with pictures using a baseball bat between tire and fender and explaining the method. In fact, I suspect it is the "rolling" back ahd forth of the wooden bat that has led to us all calling this process fender lip "rolling" rather than fender lip bending.

Comparison to your Enkei Rp-f1

Please advise me what the unsprung weight would be per corner for the Enkei RP-F1 16 x 8 with the Toyo 225/40/16 tires currently on special.

The tire is 19 pounds...the rim 14.8 pounds....that's 33.5 pounds total.
