What's best chassis mod?

* I'll second the frame connectors. (Unless that's what you were referring to with "tie bars".

* Make your 6 point cage into an 8 point with short bars behind the seats angled from the main hoop (at the cross bar junction) into the frame connectors. Tack or weld the frame connectors to/through the floor.

* Aluminum or poly front spring eye bushings, poly rears and solid or poly engine mounts with a torque strap. (It all helps the suspension work better by getting rid of the "mush".

* New rubber or poly strut rod bushings.

* Don't worry as much about removing weight from the back of the car. That's where it will do the most good and give a little extra insurance to help hook at marginal tracks. Consistency wins most races, not an extra tenth or so.

* Battery in the trunk. But then you have to get a master cut-off and do some rewiring.

* SS style springs or CalTracs if you can afford them. Pinion snubber with clamped front leaves until you move up.

* 6 cyl torsion bars.

* Shocks are important, front & rear. But they can vary depending on your level of mods to the engine, drivetrain & suspension.

* A good front end alignment if all the steering parts are good, with little of no slop. Don't recall the proper "straight ahead drag racing" specs, but I'm sure someone will chime in.
