c'mon, really? Do a search?
SWB is 210mm.. The S-Spec comes with an aluminum lower control arm mount that has 1 degree of toe built in. It also restricts you from running the medium and long wheelbases.
You can get this from Tamiya's own site:
Though the kit does come with the plastic 0 degree toe in LCA mount which enables you to run MWB and LWB...
Looks like it's a big deal, I'd cancel your S-Spec order and get a Pro instead. It'll cost you a little bit less, but you'll get the black chassis (instead of the chrome you loathe so much), buy the motor mount (which you're getting anyways), and also the 54000 TRF shocks (which you're getting anyways as well). With the Pro version you can also run whatever wheelbase you desire.
