People sure do like to spend your money, don't they? Fix the 8.250 up. It is plenty strong, bolts in right with no modifications and has plenty of aftermarket support for gears. It's a no brainer.
Below is a copied reply from another thread recently started. I'd like to add this comment up front. 8-1/4 suregrips are available new at very reasonable prices.
I appreciate that but I've consistently been steered away from 8.25" due to the C-clips, availability of components, etc...also, they're not as stout as an 8.75, no? I'm thinking that slicks might spell the end of one of those.
The 8-1/4 gets a bad rap due to the size and C-clips. While C-clips can fail, it is when there under abuse there limitations arise. If the car is going to spend a lot of time with slicks and at the track, something larger may be a good move. Normal and occasional spirited driving is fine.
I have not noticed a shortage of components or selection of ratios. These rear can hold 400HP all day long. While the 8-3/4 is a much more stout part, the price is reflected.
No matter what rear you use, there is something some one could point at as a short coming.
What is the intended power level?huh
