I just built one last night. Haven't had much time to mess around with it. I might be able to throw something together soon. But I'm sure someone here will chime in with a winning setup.

AWESOME IS-F RM tune. I won german championship with ease. B spec bob burns the tires out too fast though and cant finish the race, but for a spec, this tune almost made me ejaculate.

EDIT: riddlore beat me to it :)

Yeah what about it? Bob won the last 2 with ease but Cape ring seems impossible for this turdface. My tires start smoking after 2 laps and the opposition can finish the race without even getting worn out tires? How the hell is this possible?
 
I wish there was a tune for the normal IS-F. Not really interested in the RM version.

Gimme stock settings for a fully customized suspension on it and the current weight of the car. I'll break out my calculator and psychic suspension tuning powers...

:lol: will do when I get home today after work. Thanks budious
 
This is a tune I created for R246-Reverse, which gave me a best lap online of 1'32.5xx (ish). Gearbox wasn't fully adjustable at the time and I'd probably change the LSD settings if I ran it again, however, the car was still quick after 10 laps due to ok tyre wear.

Power - 735hp (max)
Weight - Minimum
Tyres - Racing Soft
Aero - 35/60
Final Gear - 236mph
LSD - Torque = 60, Acceleration = 45, Braking = 20
Ride Height - -25/-20
Spring Rate - 16.5/17.0
Damping (Extension) - 7/7
Damping (Compression) - 2/5
Anti-Roll Bar - 3/7
Camber - 2.0/0.0
Toe - -0.20/-0.25
Brakes - 5/6
ABS - 1
All other aids off.

Hey Budious.

Here are the stock settings on a fully customizable suspension for the IS-F.

Ride Height is 0 for F&R.

Spring rate
F: 11.6
R: 10.5

All damper settings are 5.

Anti-roll bars are 3 for F&R.

Camber is 0 for F&R

Toe is 0 for F and 0.2 for R.

Thanks a lot. 👍
 
Need current weight also, after any weight reductions, etc.

Found stock weight on another GT stat website. Here is for stock 1690kg IS-F (non-RM), a light handling re-tune:

Ride Height: -3 / -4
Spring Rate: 11.0 / 10.0
Extension: 6
Compress: 6
Anti-Roll Bar: 4

Spring and RH are setup, damper and roll bar can be adjusted to preferred feel. Try dampers all at 7, or 5e/6c, 6e/7c, 7e/8c you might find something you like there also. AR bars probably best 1:1 at 3/3, 4/4, 5/5, 6/6 ... but you can go +1 on rear if you think more oversteer is needed (ie. 4/5)

Thanks a lot budious.

I will give your recommendations a try.

Sorry that I forgot to put the weight.
Also it seems the dealership listed weight is different compared to the actual. My stock IS-F weights 1623kg while the dealership says 1690kg :lol:

Hmm... no weight reduction 1? I have seen other inconsistencies though, even cars that labeled one cost then another was deducted from my credits... so I won't even argue the fact. I'll go buy one, but so long as the weight distribution is the same at 1623kg as 1690kg it shouldn't affect the handling too much. Actually you can do the weight reductions if you want to, it just makes the springs proportionally stiffer to the car in comparison and may unoptimize the spring rate / ride height setup to a small extent.
 
Hello, I currently own a Lexus IS F concept 08 and am having trouble winning the cape ring. Any suggestions on the tuning to make me bring home the gold.
