450pp and racing tires? Try it on some sports hard or medium. That will give you better results for tuning. Racing soft can hide some flaws in a tune. I'm in borderlands 2 now, but if I get time and can find the car I'll give it a shot

The lobby I always race in is a 450pp Racing Soft lobby...
That's why the tune is made on Racing Soft.
It is possible that the tune won't work well on Sport tires.

450pp on racing tyres...?

Well.. I can try it I guess.. not sure what I can tell you about the tune since the tyres you're using are going to be providing enough grip at that performance level to override practically anything you do to it.

-------

Even on racing tyres the car was scrubbing the fronts on some corners, after a couple of laps I had adjusted my line to minimise this problem but it was still persistent - in any endurance race this isn't exactly ideal.

The diff felt very solid on the racing tyres, I was able to throw the car into corners rather cleanly with no fuss and a pleasing lack of under steer.

The suspension does a decent job at holding the weight - however it felt very susceptible to rapid weight transfer which upset the balance during strings of corner. Adjusting my line solved the problem, however it was not only costing some time but I can see it becoming problematic while maneuvering race traffic.

The gear box is fantastic, it provided the torque that I asked from it and none of the gears really felt too long or too short.

However - the entire car fell apart upon lowering the tyre grade. Understeer prevails in a very severe way, there's a big lack of front braking force, front tyres are practically on fire while trying to take tighter corners with any degree of speed and the weight transfer went from a mild inconvenience to down right dangerous.

I understand that you're only using this on racing softs and you didn't intend for it to be driven on sports hard tyres - but the fact is your tune is currently heavily relying on those racing tyres.

In short - it felt really quite good on racing softs with a brilliant turn in and good grip all through the corner, it suffers from excessive weight transfer when the car is unbalanced and could do with tightening up at the rear possibly. But the fact is it's relying so heavily on the grip provided by the tyres that it's going to start feeling unstable as your tyres lose grip.

...

Thanks for the review! 👍

First off the good things, the gearbox and LSD.
After reading your comment, I see that those are good as they are.
I won't change anything about these.

Now the not so great things... The suspension.
What do you mean with "scrubbing the fronts on some corners"?
Sorry, my English isn't the best.
Also you say the car feels unstable and understeers quite a lot.
What can I do to make it more stable and to have less understeer?

Ahh, what I mean by 'scrubbing the fronts' is that I'm having to turn my wheel a great deal more than I should while taking certain corners even when taking more gentle lines to compensate, I know without looking at the indicator but if you're unsure you can look at the tyre indicator at the bottom left, if they're red that means they're scrubbing and wearing out.

Doing this isn't so bad with tyre wear off though from my experience it slows the car down as you're essentially burning away grip and the more you turn your wheels the less grip they have to apply power - with it on however it causes needless wear. There isn't really any one thing I can suggest to do in order to stop this, I don't seem to get this problem with my tuning so I'd assume it's just how the overall set up has been down.

For the suspension I'd personally tighten it up a bit, you're on the right track with your set up as you're properly compensating for the weight distribution 👍 however it feels very loose for how much weight it has. Raising the spring rates should help solve this.

I'm just looking at your suspension set up and I noticed you're running -22 -20, I just thought I'd check: are you trying to shift weight to the rear? (I'm assuming you are based on your ballast) how you currently have it is working against you as having the front lower than the rear you're shifting weight forward, doing this is just making the extra weight you added less useful.

So try setting the rear spring rate up a little higher and work from there, I've never personally had the extension rate lower than the compression but it seems to be working for you, maybe try playing around with that though.

I'm sorry if my rambling isn't very clear, I understand all of this stuff in my head but I really seem to struggle while explaining it to people.

I don't know the range of spring rates for the Spoon Integra, so suggest you set the front at 70% of maximum and the rear at 35% of maximum.

If the car understeers on entry, try reversing damper compression settings. It could be tyres are overloaded and this might help slow the weight transfer to front allowing tyres better grip. If the tyres aren't overloaded it may have the opposite effect.

When tuning the Spoon Civic I changed my usual negative front toe values for a little positive toe and this seemed to help grip through the middle of corner.

If you plan to try the car on Sports tyres, I suggest lowering Initial and Decel values on your LSD to help eliminate understeer.

I understand what you mean.
I will try and test some more and try to update the tune in a few days!
Thanks for the help!

I will look at you tips amd test them out.
