Here is the data. Looking for the best performance gear with this combo and/or DR's.

5-speed
Vortech HO 11 psi.
275/40/18's

 

If you're gonna run 275/40/18s at the track and on the street, then get 4.10s. I love mine with that tire size. However, when I go to the track (not very often) I run 275/40/17s, and with the smaller tire I wish I had a different gear... but a taller tire like the 18s fixes that problem.

The 4.10s with a Vortech and 275/40/18s on the street is a lot of fun, and I still get around 23 mph on the hiway.

 

Agreed.

 

4.10's for sure! Call me for package deal with 4.10's, install kit, royal purple gear oil!
