Hey guys, been real busy, got front lift done gonna do rear ASAP... still havnt found tires

 

i'm running about a 3.5"lift on my 99 with 33" tires and some fender triming. so far so good. i get about 11mpg in town with the stock 3.55 gears, its the same milage i get with my 92 and 31" tires.here's a crappy pic of mine but you can kinda get the idea.

 

this is my 92 with the same lift and 31" tires on it. only had to trim a small section outa the front flares.
hope these two pics kinda help you out.

 

Stick to a 10.50 tire and you'll have no problem.

Here's mine on the 34s

 

What tires and lift?looks gooood!!

 

See sig

I also moved my axles outward about 1.25"

 

Yeah I had to heat up a razorknife and cut out the bottoms of the front flares where there is a bolt that attaches to the fender it took me 5 minutes tops and it did wonders lmao.

 

I run 33" 12.50s on stock 7 inch rim with wheel adapters. Hacked wells way beyond pinch weld . Bumpstopped. It tares pretty good its just a beater so i dont care about the pinch weld. I just unloaded cans of spray foam up in there

 

how much did it cost you to regear?

 

that look sawsome! the only thing holding me back from bigger tires is the earing issue... thoughts? cost ? ect... thanks!

 

ya it can be done i have 35s wit 4.5 inches but after you cut ur body u gota get flares so ur tires dont stick out n cops dont give you a hard time

 

Gearing is a good question. What is minimum gearing for 33s? I've got the crappy 3.07s on my AX-15 (manual trans) and don't know what to expect with 33s. Any thoughts?

I don't notice much of a difference from stock, running 31s and 3.55s.

My guess is the 33s will make a little more of a difference with torque and gearing. I'd probably suggest swapping to 4.10s just to be on the safe side.

 

The formula: MPH x rear gear ratio x 336 / tire height x top gear ratio = rpms at speed

70 x 3.07 x 336 / 33 x .79 = 1728.57 rpms at 70 with 33 inch tires

70 x 3.07 x 336 / 28 x .79 = 2037.25 rpms at 70 with 28 inch tires

I gave you the rpms for 28s as stock that is what is on mine. There is a difference of over 300 rpms, you can use the formula to figure out what ratio you want to run.

 

so i have a c8.25 which i have searched and found is a 3.53 ratio. after doing the calcs with 28" i get 3753rpm at 70mph ( i think this is wrong)
and 3184rpm at 70 with 33"s

did i mess something up here
