I've been having a bit of a hunt around, as this has intrigued me a bit
I can't find anything saying about SAYC on the TME. Don't the cars need the active centre diff' to run SYAC, to shift the torque front to rear? The MLR model comparison states that they both have AYC. Apparently though, the pressure switch in the AYC pump is different between the GSR and the TME. The TME's also have the LSD front diff', as found in the RS, and some of the GSR's (due to Mitsi' running out of open front diff's).
Re the suspension, I've read more than once now that they reverted back to the Evo 5 setup. And I've just read that the TME uses the Evo 5 front arms, with the ball joints pressed into them, instead of the 6 GSR's bolted on items. They do have a 3 point front strut brace as standard, which was an option on the GSR.
The following was posted on the MLR, by Co-Ordsport, who were linked with Ralliart UK:

'Front struts, front springs, rear shocks, rear springs, front lower arms, AYC pump on the GSR, Crown wheel ID is bigger in the transfer box, one of the bearings is also different in the transfer, I'll post more when I can remember. And seats, front bumper, dash clocks, turbo, exhaust, the obvious stuff.
The chassis no. should also start CP9A 020'

Don't worry, I'm not trying to argue at all - I'm trying to learn. I don't know Evo's as well as I know gtt's (18 months experience of Evo's VS 11 years of gtt's, means a long way to go) I want to get some info/books, and get reading
Shame you crunched yours. It's never good to hear
