Mk4 torque bushes - job done.

Hi Everybody, I have just added the extra rear sub-frame torque bush in accordance with David p's recommendations, just for the uninitiated members, the NA's have just one torque bush to handle the 220BHP, so if you are going NAT, and doubling the BHP, then you upgrade to a second bush, as per Toyota did with the TT model. The consequences of not doing this is abuse and possible failure of the diff and drives.

Many thanks to David P, he must now be on a par to Chris Wilson. Herbie.

You learn something new every day, I never realised that the NA cars only utilise the one diff rear bush mounting. These are pretty important bushes as they fight transmission hop on power down or power off and when I did my underside refresh of all the £10k spent on bits and bobs the only parts that really did look like they were past their best were the two rear diff bushes that were rather soft and spongy compared to the new OE ones that replaced them. If people want to stay stock they could probably do worse than hold a spare rear diff bush or two while you can still get them, well you could in 2018.

Nice work, I got a second one added to mine when I addressed the underside. For all it must've cost Toyota during production, it's a bit strange that they decided to do without a single bush. Literally everything else is the same underneath otherwise

We cant complain though mate. The GE performs just as well and the diffs handle mega power too.

Yeah definitely mate, counting my blessings with all the kit they left under there for us. Just doing without a single bush is all that confuses me lol
