After months of trying to get this car to drive how I want it to, I've almost got to the stage of retiring my T4. The problem I'm having is a very unresponsive steering mid corner and general lack of steering. Every other xray I've owned has very responsive steering through the whole corner, initial and mid. 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.

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!

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.

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.
