88 S-10 Blazer Baggin

I've got a question. what's the biggest wheel someone has run with no bodydrop and keeping the heater and ac? i'm pretty sure i could run 18s no problem but i'm wondering if i would be able to run 20s with out having to tub out the fire wall? if anyone has pics that would be great.

you have to tub out the firewall for 20's.. you can lay frame on 18's, but u need a slight tub for 20's along with a slight heater box mod and you'll need to move the wiring bulkhead on the drivers side.

even with no bodydrop?

yep. you have to notch for 20's on a newer style just trying to lay frame, 1st gens have less room.

my 205-50-15 was within 2" of hitting my heater box layin frame.

another question is how big of a wheel can you fit in the rear with just a c notch? i kinda want to keep the back seat. any ideas? i'm thinking about runing a 17 or maybe a 18. what would fit the best? and still lay frame.

anyone have pics of the front and rear set ups in blazers?

matt if u wanna come look at mine u can i can lay 20 in the back with seat and no hole in floor both my blazers have no cut floors and lay little mods in the front and u can be fine wit a small tire 88 lays with a 225-30 -20 withmodded box and ac
