This T4 however is completely different.

I've tried, every spring combo, 2.7fr2.7rr.... 2.5fr-2.5rr.... 2.7fr-2.3-2.6rr.... 2.5-2.8fr-2.5-2.8rr, even harder rear springs than front lol. Bump steer shims upto 4mm, caster 6 deg, graphite arms, harder c hubs, different shock oil, gear diff oil upto 2000 and car still has similar basic feeling of numb mid corner.

Anyone else suffer this?

I've done well, getting the car in A final at EWS in the UK every time I get a chance to race there this season which is usually an open indoor track, but at my own club where its a lot more technical I struggle with setting it to feel nimble and have steering mid corner on hairpins. It's like it's a limosine. Tried even + 0.75 rear blocks and LTC-R shell which just seems to turn in and feel even worse mid corner. The only good improvements I seem to have is with the Subaru Type C body and front gear diff with 1 million oil which is still not where I want the car to be. Any further ideas would be a great help! Thanks.
Another driver from ews that tried the t4 but went back to he's 3 12 that now drives a yokomo hopefully you'll know who I mean if not pm me! had the same issue he felt the car lacked mid/exit steering he described it as unable to go around a corner in a smooth arc!
As I said above he went back to he's 12 and done very well with it now running the yokomo goes even better!
He said it felt to do with the lack of roll or weight transfer. I have felt a couple of times I really need more steering, try running the wheelbase short! It makes it feel a lot faster but my consistency and fastest lap were near identical!
Hagberg struggled at the ets, if u look at the video what little u see of he's car it looked slower in the corners!

I have a easy question.

Will the 2011 T3 sway bars work with the T4? I hate to order new swaybars.

yeah they do just lock in the retainers between the bulkheads sto prevent the swaybar from shifting (I am not sure what they're called)

Rsd offers those in a more attractive package and I'm sure they are cheaper.

Yes, I mentioned it in the post. It's still on the car which seems to work better, but its still not right. I even shoved on 50mn cvds at front which helped a tiny bit as well to make it more responsive. Still feels lacking though.

I have droop set at 5.5 and 4.5 on droop gauges. Surely running that much droop will get it so stuck to the track it will loose even more corner speed?

I tried it for 2 weeks but I just found it to start twitching around through the chicane so I put back to stock. Surprisingly it didn't do much to the handling. If I tried that on the T3 2012 it would've been very hard to drive but the T4 doesn't change it's frustrating characteristic.

We did this to mine and it came alive. We moved the rear AND front arms all the way forward, set ride height to 5.4mm, set droop with the chassis on 10mm blocks.

Here's what I changed for better corner finish:
1.3 front bar
2mm ackerman shims
450f 400r oil
kit springs
5.6f 4.8r droop
5.2 RH f&r
22 deg steering travel

Turns very well (even with a spool) yet doesn't lose the rear. JMO

Interesting... The 2mm I haven't really tested much as my car wanted to snap initially on throttle but I didn't give it much of a chance. 1.3 front bar is too docile but 2mm ackerman I can understand would counteract that.
