Which 9" for metric car 58"-60"-62"

[Dirts4Racing]

I am going to replace the 7.5 rearend and put a 9" under my metric street stock. Need your help. Which is the best to use 58"-60"-62" and why?

[cheaterleaddog]

Depends on what your rules say about rear end location. Do you have link to rules?

[Dirts4Racing]

Stock location per the rules

[Dirts4Racing]

This car is new. the stock rearend is not durable and prone to breaking axles. This is the reason for the 9"

If a "Builder" built this car, then Put in what he has proven to work. If this is something that you just purchased and some guy somewhere put it together, good luck. Many people run 60 - 62 in a metric. I used a 58 but my car was built for it.

I would say wider the better just to keep the brake caliper away from the frame rail...

[Dirts4Racing]

Hurst, why is wider better?

[racer67x]

if you run an 8" tire you could get away with a 58"...if you run an 11" tire you will need the extra width to keep the rr tire off the framerail.
measure what you have now and if it works get the same width..

[Hurst390]

For the reason I mentioned...If you have your right side brake caliper mounted above the centerline of the axle tube it will end up hitting the frame rail. The wider the rear housing the farther away from the frame the caliper will be. You can manipulate your desired track width with wheel offset.

We run 2 cars in street stock. One has a 58" and the other a 60" The 58" had to use a 2" or 3" backspace wheel with a 1/2" spacer.

62" with right side caliper as close as you can to frame without hitting.

With all the different replies I will evaluate my options and make a choice I can live with. thanks to all of you for your time help me.

Calipers get mounted at angle to not hit frame.

Tire/caliper to clarify
