Probably close to 200 mph down the hi way with MT Pro Radials at 30 lbs of tire pressure. Gets a little floaty at that speed tho so I wasn't there for long.
I like Racestars cause they are more durable. Yea they are a little heavier but imo stronger and less likely to bend from Pot Holes. My car is a dedicated street car so having bent rims on the street is something I try to avoid.
I had a set of Bogarts on my previous Mustang and I hit a pot hole with those and my rim bent really bad! Its a badass lightweight wheel but not very street worthy imo.
Here in New England Pot Holes can swallow dump trucks whole.....
