Koni Yellow Sport AutoX setup

cruzthepug · 02-13-2015, 07:08 AM

For those running Koni shocks for AutoX, what is your setup? I think stuy486 posted he was set at 60% front and 80% back for Nationals last year.

How stiff do you run yours? Do you keep them the same every event or do you vary your adjustments?

I think you'll find everybody is a bit different, and there are a lot of "it depends" factors. Some of those:
Is the car otherwise "Street" class legal?
What front sway bar?
What size and model tires are you running?
What type of surface do you run on, and what style of courses?

Jeff's stated settings sure seem like a great place to start. But what's best for each person and their situation will differ, so it's worthwhile to experiment and lean the cause/effect patterns of shock setting changes.

The biggest thing I ran into was that when I went too stiff in the front, it started getting a lot more ice mode under heavy braking on asphalt lots. I never had ice mode problems on concrete though, so perhaps stiffer in the front on concrete would be alright.

Where did you get yours from...cheapest?

Can't go wrong with pro parts.

All my local events are only a few miles from my house and I plan to set the rears while I'm changing wheels. I'll also be doing a bunch on events that are 70-100 miles away and can't decide on setting the rears stiff before the drive or taking my jack and setting them on site.

Opinions?

I set my shocks sometime last summer for the last time and have driven on them that way ever since. They're really not that bad on the street, I've probably put 8k miles on the car since then.

cruzthepug · 02-28-2015, 07:27 PM

Test & Tune today. Started the day with the shocks set 60% stiff front and 80% rear. I was all over the place, like driving on ice. Tires (Rs3's) were brand new with about 20 miles on them, so I attributed the lack of traction to that. Today's T&T had a short timed course and in a different part of the lot there was a slalom and a skid pad, so I headed there to scuff the tires.

When I returned to the course it was better in the front but horrible in the rear. I started lowering the stiffness of the rear and it got better and by the end of the day and multiple adjustments, my times were just tenth's off the times of the vette and s2000's in BS. Final settings were 70% front and 30% rear. Headed to Birmingham in the morning to ALSCCA' T&T, should be 15-20 degrees warmer, so I'll see how it goes.

Ended up going a little softer in the rear today, down to 20%. Pleased with the results. http://youtu.be/xrMixSF-NJw

Just practice, but 7th fastest raw time and 3rd pax.

What sways are you using? Camber settings? And what spring rates, OEM?

cruzthepug · 03-02-2015, 01:33 PM

Eibach front sway, stiff setting. Factory camber, OEM springs.

I would guess that the limiting factor is going to be the factory spring rates. They are pretty soft by AutoX standards from what I have seen the other guys here like to use. Eibach front an OEM rear bar should be a decent setup for sways. ANY sort of spring upgrade you could do would help a lot though. Anyone at a "just past beginner" skill level is going to outgrow them quickly. Even just a set of Spec-R's is going to help. Also, if rear is coming loose, lot of people have claimed replacing rear diff bushings helps. I would also suggest try disconnecting the rear sway bar completely. Just disconnect one of the end links for a session or two and see if you like it better.

Leave the rear end soft. Even though it might not "feel" as responsive, sacrifice some "stiffness" for some grip.

cruzthepug · 03-02-2015, 04:30 PM

At the end of the day Saturday I was a little loose in the rear, the softer adjustment corrected that sunday. I'm just a bit pushy in long sweepers but good everywhere else. I may try a 1/2 turn on the rear to try to split the difference, but I'm sure ever thing will change once the weather gets hot
