Part 2, M2 and Cayman get murdered (unfair conditions though).

Each to their own but having had my 2nd driftday yesterday with my M2 I only can say Jethro hits the nail on the head. I know it's a repost but it also shows 'fun' and 'feel' , 'balance' and 'playability' are rather important in a sporty car. I think it makes a sporty car. Anytime M2 for me it's fantastic as a throw around high speed drift car .

I wonder what type of adjustability and playability you could unlock modding a TT RS...

How complicated would be it to make it a drift happy car???

In the movie Tokyo Drift, they removed the components to drive the front wheels in the Evo.

They also had to boost power to the engine to compensate.

First you go to the nearest BMW dealership.
Then you trade it in for an M2.
Drift happy.

The AWD is haldex based. You can tune it to a point where there is less understeer, but it is still a FWD biased AWD system.

The easiest way to make it drift happy would be to add snow.

No matter what you do it will never do powerslides or power on oversteer. The power split it at most 50/50 between front and rear, this is when the the haldex diff is completely locked, and due to mass transfer the fronts will always run wide before the tail sticks out.

Didn't you know? Now it can send 100% to the rear.

At least 80%.

Very interesting that M2 can keep up with TT on track. Would have been interesting to see a M2 with DCT and M Performance Suspension.

At least 80%.
It's 100% of the torque that can be transferred to the tarmac (not 100% of the power) that can be sent to the rear. This happens when the fronts are having almost 0 grip. The construction of the system is not allowing more than 50%, just give a little bit of thinking. You don't have a transfer box but a fwd car with a shaft coming of the the gear box connecting the rear wheels open diff with a haldex coupling. When the haldex clutches are 100% engaged you and up with 50/50 split. The commercial can say and it can fly upside down with the new haldex but it's not always the case . Beside this where is the 100% rear when the fronts are pushing wide under power?

The only thing that can improve the driving dynamics would be a locking rear diff. But it's very unlikely that someone will ever produce such a diff (did a bit of research since I switched to the M2 from a pending Golf R order and I contacted Wavetrak, Qualife regarding the rear LSD)

DCT M2 would've beaten the TT time, with or without the coilovers.

I wish they added the C7 'vette to this, why haven't they?

It would have the fastest lap for sure, it's a real sports car and costs the same as these.

Yes, it's on their Drivetribe site. I googled it and it appeared. Just over 13 mins long, he goes on a bit rather than really getting onto the nuances and the conclusion is as expected.

I do wish they'd tell us what spec the Cayman has, especially what chassis/diff options are fitted. Nobody ever seems to drive a non-S without torque vectoring/PASM etc.

So I am in the market for a used 2018 TTRS. In my country, a used 2018+ M2 Competition is about the same price.

What is going to be faster in a straghtline from a Stage 2/3 TTRS on pump98 or e85 fuel, vs a stage 2/3 M2 Competition on the same fuel?

From my initial research, it seems the TTRS is faster especially when tuned. But I do like the front end of the M2 better.

Opinions?

After owning a stage 2 tuned TTRS with a built engine which was mind bendingly quick I'd rather have a slower M2 than the quicker TTRS. It's not that great to drive outside of the straight line acceleration which gets old quickly. The front end of the M2 is mostly devoid of feel but the TTRS is even worse in that regard.

What numbers did your built TTRS lay down, and did you ever run a 1/4 mile from it?

It was not even close to the level of some of the TTRS out there, though it did have an Iroz Motorsport built engine. About 500 crank. I ended up finding a lot of fault with the handling and I parked it a few months after getting it built and it sat outside from the moment my 911 came home to the time when I sold it. I did not bother getting the 1/4 time from it as I took it off the road soon after build, realizing its not the car for me.
