7.5 axle
well, it's not recommended for everyone, but this is what I did:
budget buildup - 7.5 Monte axle...
->Richmond 4.10 2 series gears $193.00
->Summit mini-spool for above $97-99.00
->install, either self or garage - 4 hours or $200.00
->used tires - free
->lower air pressure about 5 - 10 psi so it doesn't squeel as bad when going around corners.
*-> it's bearable and cheaper if you don't mind an occasional squeek around a corner. you don't necessarily have to be worried about twisting an axle or "turning wide" as some do with a spool...just air those tires down a bit. I drove mine on the street for 2+ years. HTH and e-mail me if you have any questions...
Mine has lasted for over 100+ 1.7 60 foot launches ( and lasted on a 200+ shot of spray, but NOT at the track). At the time this is what I did to stick to a budget. There are trade offs either way. I have yet to see an 8.5 for under 800 dollars but there are always some "deals" out there or someone who needs the money.
I've seen some 7.5 bust while others last. Some parts have flaws while others don't.
