I use Redline ShockProof Heavy after all the busted thrust-washer stories R154 users posted online .

 

I would like to know how shockproof heavy feels. I heard that the solid particles also tend to gunk up together and stick to the case.

 

Explain?

Is it because of the diff swap gearing?

So you're saying an SC300 on stock diff and 400hp will feel even faster then 500hp after swapping an SC400 diff in?

I'd assume that on low end but he said he only does highway pulls, which i'd imagine you'd want to stick to SC300 gearing.

I'm not arguing I'm just trying to figure this out and learn some, because I plan on building my car around 450hp. and plan on swapping in a TT auto diff. I want more low end torque

 

with an inline 6 you will have to sacrifice quite a bit up top to get "low end torque"
forget about the low end and keep the gearing nice and long on a manual transmission so you can stay in boost longer.

 

any good sites that sell the redline fluids? i cant find em on any auto shops like checkers. =P

 

royal purple 75w90 here in both my tranny and diff.
