Unlimited access to a machine shop-what do i make?

[IRON-E]

I vote for the 5 lug hub & I think you can purchase full blank rotors to make your own lug patterns too. :)

I'd jump on the 4 to 5 lug swap attempts every other new member with access to a machine shop tries to jump on.

Cool idea, would be helpful, and profitable.

Also I was thinking seat adapters, maybe something specific to Vaders? (especially the rear since it's hard to get them to sit right)

The coilover idea would be cool, if you really wanted to make an investment, get a group buy from BC/Megan/etc and fabricate them to be plug and play like GC does. But there's probably not a huge profit margin competing with GC and their reputation.
