20's, now should I go with 4.10's
I have a 99 with the 3.55 gears, I put on some 20's and of course that slowed it down off the line.
Should I go all the way to 4.10's or go for the 3.73.
Anyone know how much rpm the 4.10's increase on the highway.
I guess I don't want to loose too much m.p.g.
Thanks
Chris

410/355= 1.1549295774647887323943661971831
15% higher RPMs according to my math
295/40-20's are about 3% larger.
Net = 12% higher RPMs.
I moved up from 3.73s, and I am thinking about 4.10 gears with a Gear Vendors .78 overdrive.
