Lap Time Gain: stock rims to 18x11 and 18x12's (good tires both)

[Silver Bullet]

I currently run the stock rims with the Toyo RA1's on there. A little better than stock maybe a second a lap it seems.
Am going to these bigger rims with Pilot Cup tires on them. 295/30/18's and 315/30/18's.
I think the cups would even be a tad quicker anyway but was curious anyone have any idea on a 90 second course?

May be a wasted point as the guy in the for sale area never seems to want to put in one ounce of effort to sell them. All he has to do is look up shipping amounts and I am there but I think he is hoping someone will come and pick them up.

I will depends on your suspension. If you suspension is set up to take advantage of them you will get a big gain. 1.5 is easy to gain.
