Usually rear tyres off balance the whole car vibrates not the steering...

Bro, i think the problem might still be your drive shaft fitting.. i had encounter this before but on my RVR engine.. the same as what you describe just tat my speed is when 100km/h above.. till the whole dashboard also can feel even i accelerate till 170km/h still same.. went back ask my fren to check, he says one of my drive shaft(can't remember which) was 3mm longer.. so change to a shorter one so that it'll have some free play inside and not direct snug fit when i accelerate. And that solved my problem ever since. So not sure bout your TT.. Although it's same engine like what bro Danz fitted, but maybe due to some unforseen reason, the drive shaft could be too tightly fitted..

the latest troubleshooting pointed at rims not ok. bout the fitting, maybe need to give it a try too. that will be another 10 more days. im going to bring to a more reputable shop that better with modified car.
more suspense thing is today one of the brake rotor jammed. pulled aside, wait it cool, spray some wd40 and pump it. voila.

brake oil flushed all 4 corners not long ago. what would have caused it by the way?

Center cone already fitted, right? That should centralized the rims already....

You flushed the brake fluid but did not service the calipers, right? The pistons could be dirty or rusty so when brake was applied. the piston came out, but could not go back in therefore in contact with the disc and jam up.
Also check and clean the floating pin. That could jam also if it is dirty with brake dust etc....

late update. the rims abit bengkok already.

on brake part, caliper piston and pin serviced with my old man. now running good.

also, previous owner might not flush those fluid on time / regularly. as far i know, brake oil is hydrophobic, not sure if thats the correct term where it tend to absorb moisture. so eventually water will get in the system and rust things up.

and, i have extra set of driveshaft , recond unit. any takers? hehehe

I think the word is hygroscopic. Hydrophobic is more like repel water.....
