can you use a full spool on the streets if you have a manaul 4x4 axle in the front
Absolutely not! If you had a spool inside the front differential you'd eat-up your new set of tires in less than 500 miles. You'd tear the axles right out of the front center-section to boot.The front tires would squeal and jump all over the place as you steer less than 5 mph. If you bought rock-hard rear tires for a rear locked differential, they'd be gone in 1,000 miles. You'd never be able to turn sharp corners on black-top. If you had a custom built third member with short axles rear tire life would be a bit more. Black-top modified race cars have full spools in the rear but the left rear tire has 2 1/2 - 3 inches less circumference to help the car steer left all the time. The larger the track with sweeping corners the less tire stagger you need. Tires last one to two nights of racing.
its harder on the axles and tires and may tear up fresh pavement when you take corners but yes you can drive it on the streets. just take it easy till you get use to it because you never know which wheel is gonna hook up and which wheel is gonna spin. P.S. i assume you are putting the spool in the rear. RE: Additional Details you wont have any problems with that. it will drive the same as it does now.
