full length or standard length subframe connectors?

[Skankin]

The front subframe doesn't look much stronger than the floorpan... I'd go for the full length, and tie the suspension pick-ups together.

I've got the Western Motorsports SFC's. Griggs, Global West, Maximum Motorsports & Kenny Brown all have decent SFC's.

I wouldn't bother with the ladder/matrix bracing though... it looks like a lot of added weight, for little benefit. If you think you need it, you should go for a roll bar (that'll really add to the torsional rigidity). Some of the 4 pts aren't that intrusive, but a 6 pt would certainly be better. Kenny Brown's RB doesn't look like it'd get in the way... it's thinner & lighter, but doesn't cut it for some of the faster NHRA rules. For street/autocross, it looks pretty good.
