Need help with 2 issues but same place!

The clamping in a streeter does pretty much nothing. With a 440 even less.
You are waaay past clamping, while being waaay under-tired.
Street launching pretty much requires a dedicated suspension set-up, and buckets of money.

What CAN I do to make it hook the best it can? I don't have gobs of money but surely there is some little things that can be done to help? The spring clamping doesn't help? Im working on helping the tire situation..
