I might as well post my tune, bare in mind I've accumulated over 3000 miles on this car since December, continually tweaking it over the months for my personal style.

I usually take influence from real life tunes and then fine-tune from there.

I received advice on my dampers from @Garage Yokomichi who have a tuning garage on GTP, and a real life garage.

Hmm a good dude name @PUSH once said, "Try drifting/driving it stock first to feel what it might need changed, rather then trying to tune it from the get go" (something like that) So I did and after 3-4 hours straight drifting my chaser, I came to this tune and im NEVER changing it!

Tires: CH
Ride height: 84/82
Spring rate: 19.12/14.91 (I think that's stock rate on [custom])
Compression: 5/4
Extension: 5/4
Roll bars: 2/4
Camber: 2/1
Toe: +0.45/+0.30
Brakes: Racing: 7/4

Transmission: I did a tranny flip. Top speed maxed out. final gear maxed out. top speed brought back down to lowest point. set final gear to 4.555.

1: 2.337
2: 1.695
3: 1.345
4: 1.110
5: 0.943

Drivetrain: 60/60/60 diff. standard clutch. carbon drive shaft.

Power (My tune specifically) set limiter to 97.5%
Standard engine
standard computer
Semi-racing exhaust
Standard manifold/Catalytic Converter
ADD intake
Low rpm turbo
NO NOS

BODY: DO full weight reduction. Then add 129kg to the rear. also wingless

Final results: 505pp 400hp 453ft-lb trq 1,350 kg 51-49 distribution

Also I have a video of it in action on my YT page.



Hope someone with a wheel try's it! id like to hear their opinion.

The chaser is one of the cars I had some trouble with.

It seemed I could never retain control over the cars rotation once it had gone 'too far', but this limit was far earlier than other cars, and made reverse entry stuff pretty much impossible.


My current tune works nicely, but I can't bring myself to run this car at anything less than 500bhp, it's currently at 650+,and can handle the high speed stuff beautifully, but also still works on the mega slow stuff (willow Springs hairpin short course)
 
IMO the chaser is dam near perfect when you buy it. I have one completly stock with just lsd, drive shaft clutch and flywheels. And Another one around 420hp same parts but with turbo upgrade, and full tranny. The cars only downside is gear bog between 2nd and 3rd. but this is easily fixed by moving the gear ratio closer

Bravo! Awsome set up bud. Tried it out last night. I too, have been using mr. Suspension tune for the x540. But I noticed, the tune he gave me differs in your camber, toe, and dampers.
To put it short, my chaser is now more comfortable sustaining longer, bit more angled drift. Maybe it is due to your dampers and or camber and toe, but I am liking it.

My previous ride height were set lowest possible on both front and rear. I believe your adjustment to bit higher front end has helped specially in a rougher tracks vs. Flat tracks. It feels more versatile.

Anyway, thanks for sharing. Now I enjoy taking my chaser out for a spin more often in various tracks instead of usual tsukuba.
