These are only my opinions. I'm also using the Maxx struts but using Koni inserts. 944- probably too much time and effort for what its worth. They're coilovers so you have adjustability and you can use pretty much any insert you want. If you're going to go fast you need to stop. 944 brakes are a way to go. you can use all the way up to GT2 6-pistons if you want. However, remember you're stopping an 1800 lb. car. For the rear I'm using stiffer torsion bars, swaybar and probably a KC brace if I don't integrate my cage for this function. I'm not too familiar with rear coil-overs for Bugs. You can do whatever your wallet desires. I'm using stock VW arms in the rear. They are the same as 944 steels only without the camber adjust. Alloy arms will widen your track by a decent amount.
Fuel injection. I'm using SDS. Easy to use with a handheld programmer. No laptop needed. You don't need a laptop unless you want data acquisition and pretty little printouts. Unless you're racing, you really don't need a laptop controlled system. This one has everything you need.

Your oversteer/understeer problems will result from your suspension set-up. I wouldn't say it has to do with your car being late or early.
I believe the mags. still aren't getting that there's other things out there other than drag-racing. Supa's right. Drag guys don't get it. I'm building my car for the street and occasional (road) track time. Sure I'll take it to the strip too, but its hard convincing people that I'm not building it to drag race. Take a look at Jak rizzo's car also in the "featured car" section and you'll see what I mean. Good luck dude!!!!
