Got a track related question? I'll try to answer.

I have all traction on, and when I take a sharp left hand corner on approach and then while exiting the corner my traction light is going ballistic and im not even cornering fast. I then want to power out it seems to not have traction. would going VSC help ? my thinking is that if its losing grip with traction on with it either on off or VSC it will be worst

My current setting for the KW V3 are

Rebound Front 13 from hard setting
rear 14 from hard setting

Bump F 8 from hard setting
R 12 from hard setting

I read up and well when they say rear is losing traction should soften the rebound which I did from 10 to 14 and still the car just feel like it wont put the power down.

I was also advised that to chase the grip I should adjust the compression on the end that lack grip. but then reading more forums they tell you opposite increase front end compression? so confused

Only on left? What about rights?

There are two schools of thought on this. One is to have the "stiffest you can get away with", and the other is the "softest you can get away with". When you really look at it from a big picture, they're really variations of the same thing: maximizing contact with the ground.

When you're limited by budget to only making major changes, you have to ask where the compromise point is, to get the desired result.

What setup are you on now?

What setup are you on now?

As it stands now JRSC, Ft86 rear LCAs, Flex Tein Z @ 3 clicks from stiff, grimspeed strut brace on 18x9 Rotas with PSS 235 40 18, Ferodo Ds2500 pads and Velox front splitter w race package. (Velox rear diffuser soon)

I think for my June event I'll experiment with a softer damper setting. My following event will be in Sept where I'll have the lighter wheels and Maxxis tires.

Hi

the fronts are set equally L & R

I'll upload a youtube link and you can see where I am struggling on the track.

I had quite a bit of success with another track beating my PB (VSC Sport)

Rebound L & R Front 5
Rear 6

Bump L & R Front 6 (KW standard setup)
Rear 6

I apologize for the confusion; let me clarify.

Does your VSC act up for both left and right turns, or only lefts?

yes both left and right but embarrassing I have left them all on.

my thoughts are even If I had them off, I would probably have to use throttle control and ease off anyway due to lack of rear grip.

the day was perfect condition track was not damp at all

can you clarify one thing for me, lets just say that I have all electronics off, and my rears are still twitchy on corner exits.

1. increase Bump on the rear ?
2. increase Bump on the front ?

My main issue and fixation is the bump ? its like does it really make a difference or am I just chasing my tail around.

most other coils will just deal with rebound and be done with it.

while I have read the setting the bump to go soft then harder till it side hops etc then dial it back 2 clicks, however the tracks im on are not bumpy. the only bump is if i mount a track curb

I need to know under what condition the rear is twitchy. The best way to show me that, is with a datalog, that includes OBD2 and accelerometer data. AIM Solo DL is the popular unit for this platform.

You're looking to adjust damping, but I don't know if your "twitchy rear" is from driver input, car balance, damping, alignment, etc.

Here is my link,you can see the traction light going off on the dash

Looks like you are trying to drive around the systems activating. That is the same behavior my car does on stock suspension with the system on. Try it off and see there is a huge difference.

[Northwest86]

Yep thats just the traction control system. Some of your lines looked a little jerky I guess but it did look like that was almost just the traction control inducing understeer. I didn't see any countersteering there at all so its not bad. I've had sessions on not so good tyres and it was like a drift session for every corner. For dampers you've really just got to fiddle and know what the adjustment does to the suspension. Then again some dampers adjusters don't seem to do as much as others. No experience with KW's really so I can't speak for them to much.

What recording setup is this?

I know Audi says they want it on the first 2 run groups and Porsche instructors said they are told the students should have it on.

But it also depends on your instructor. Talk to them before going out and if you aren't on the same page talk to the head instructor and see if they can find you someone to work with.

Are you serious? I guess I find that line of logic interesting considering I've never been on a race track in a vehicle that had TC/ABS/VSC/etc. (Motorcycles and Miata's on RComps, some with aero and such)

And the sport bikes were the first thing I ever did a track day on. No aids, no instructors, nothing. Best you got was an experienced friend doing lead/follow at 6/10ths to figure out the line.

I understand a true novice driver may not have the skills to catch/recover from a slide, but that's the instructors job to keep the pace within the students skill set.

I was with WRL for their Momentum School last month. A guy in a new Cayman and newer Miata, wheeling the cars around pretty decently........except they had all the aids on, even after it dried it out.

You aren't learning anything about finding grip, smooth inputs, etc, with all the nannies on.
