First off, you're gonna get a lot of people who are gonna push the TT-01. I would actually get the T-Spec over the TT-01 for the reasons you mentioned, plus the fact that the suspension is fully adjustible. It also comes with an aluminum drive shave and CVD's. Although the T-Spec doesn't have the parts support that the TT-01 does, I'm sure you can use parts from other cars when the time to replace broken pieces comes. Just my $0.02
