Hey guys, I am almost ready and throwdown on a new 9 inch for my 98 camaro. I currently have 3.23 gears which allows me to cross the finish line right at my rev limiter in 2nd gear. I race at a 1/8th mile track and my car is street legal but for fun only. It has a th350 with a 3500 stall and so far my best pass was a 7.87@88 with no tunning on my new setup. I am really undecided if I should go with a 4.10 or 3.89 gear and am debating on what length I should go with. I am thinking about going with 2" shorter on each side. I will be throwing on some 275-60-15 drag radials for sure and am thinking about a 15X8 weld wheel with 4.5 back spacing. Give me advice please. Also what kind of et reduction could I expect. I am getting a 1.70 60 ft now.

I do plan to add a 100 shot also and to also run some 1/4 mile tracks. This has me wondering if I would run out of gear. I dont want to spin my motor more than 6500.

How much horsepower do you have? Bob

450 for now but want to be prepaired for more as this thing evolves.

I'd go with 3.89 gears since you're adding a 100 shot. 2" narrower per side should keep you in the stock location. Bob

I'd actually run a 3.70 with your rpm, trans, and tire combo... it will allow a little more for you to grow in the future, especially if you plan on using nitrous.

I have a lot of customers running the 275 and 315 drag radial tires and have a ton of data from track use. Give me a call and we can discuss all the options and pricing for a good rearend package. The quickest and fastest stock suspension f-body cars are all using MWC rearends and suspension!
