The next cheapest step would be a shift light to keep your times consistant. Subframe connectors, as you mentioned. Drag radials. MSD Ingnition with a 2- stage limiter. Set 1st stage for launch so all you have to do once you are staged is floor it and you'll launch at the same rpms everytime, making your times consistant. Set the 2nd-stage for engine protection in case you miss a gear. All these upgrades will help you launch better and keep you consistant.
As far as going faster, heads, supercharger, headers, exhaust, etc....
It just keeps getting more and more expensive!!!
Good Luck. |
