Hello frst,
you will miss out the possibility to set the camber when the camber links are mounted. So you can't use a setup board but have to set the camber by measuring them before mounting. The front toe could be adjusted by pliers only when mounted or you can use two nuts countering each other. I've ordered the anti roll bar set for the front and the rear, the six alu turnbuckles, the steel shafts for the front and the alu shafts for the rear which brought me as close as 40€ to the T3 price. But I knew that before buying that car.
The T3R is slightly lighter than the T3 (even with the anti roll bars), the shocks are very good, the bearings are the same I guess, the T3R lasts and could be very fast, too. But on carpet you will NEED anti roll bars and maybe harder springs. On carpet I use the purple ones in the front.
But the T3R features a different ball diff. compared to the T3 which is not so easy to set. On the T3R you have to disconnect one camber link to be able to turn the hex screw. But that's no problem. Just the missing thrust bearing is "annoying". The one from the T3 doesn't fit so you have to put the seven balls between two washers and hope that they will stay in place until it's mounted.
When using alu shafts (stock or coated ones) in the front you have to set the endpoint of steering not by the steering knuckles as usual but by the max. CVD angle. The alu shafts are bigger in their diameter than the steel ones.
Regards,
Stefan
