Ice mode solution?

You are making your contact patch wider and your tires will take longer to come up to temp, both of which make locking up easier.

Lol. I knew I should be downsizing tires. I've been doing this a while. Can assure you I won't have trouble getting these A6s warm.

Easy fix ever heard of tire warmers.

Naw I m pretty sure 3000 lbs of car, driver and fuel will be plenty to get soft compounds up to heat very quickly.

As a hillclimber I'm pretty good at figuring out my maximum width as there is no time for tire warming. Bring rears up with a burn out in staging and with big heavy front end 315s come up to temp very quickly.

I have run this car with 285s in back, 295s, 315s and now 335. That rear end even on first few laps stayed better stuck with bigger tires. It's just compound management.

If this was a 2500 lb car I'd agree tougher to get tires up to temp but this is a heavy car. I have over heated r6 295 in this car.

Anyone thoughts on this

Rusty

Where you been? Old news that's works. It's been talked about a lot. I did this over the winter. I'll be using it on my next trackday.

I know, i know. I just been so focused on the motor aspect of my build.

Anyone knows what parts I need to get to fix the vacuum issue? Thanks.

No ice mode here running xp12/xp10 on RS-3's but after reading Dorans possible issue with the pads not releasing and understreer as a result might be my issue! My cars got horrible understeer and even worse snap oversteer when I try to correct it in a turn. I've added my rear sway back in to see if it'll help and give back some oversteer but one suggested is to put the OEM rear pads back in. Also going to check alignment, have Stance fix my rear coils for better adjustment and go from there. I still think an ABS delete and proportioning valve is in my future.

Lets us know how your results go?

I pulled the yaw sensor, and it still does not completely cure the ice mode. It cured the ice mode while trail braking, but i do not have complete faith on the straight line braking.. Also ran into SEVERE ice mode on wet skid pad which caused me to nearly go off and hit the parked trailer at shenandoah. Only "guaranteed"cure while on stock system everything + yaw sensor removal is to get grippiest tire to prevent almost all tire slippage. This is extremely distressing and made me lose all faith on braking after almost 30 track events

Few questions for you guys, the yaw switch, if done will this help out with the ice mode during straight braking? This is the only time I run into issues while autocrossing. I don't seem to remember it as bad when I was running 285/35/19 but when I went down to 275/35/18 it seems it locks up more on higher speed braking.
Stupid question but this does not turn off abs all together correct?

Rusty

Disabling the yaw sensor affects the VDC. It keeps the system from applying a rear brake caliper during cornering. Trying to straightening the car up. Which can be very unnerving. It doesn't kill it completely thou. How disabling the yaw sensor affects ice mode. Far as I know. No one has brought that up before.

ABS still works in straight line with yaw sensor pulled. However, this does not cure ICE mode completely, but it does somewhat alleviate excessive ABS intrusions during braking which leads many to believe that it somewhat "Cures" ice mode, but it doesnt. i ran into it past weekend and it scared me to death.

Tracer 09

A couple of questions here read entire thread. Want to track car with no ABS to stay out of ice mode. Have had ice mode at autox with sport tech sport pads. Took fuse out for ABS and did some low speed test runs, under 50 and applied firm brake pressure and car rear wants to jump to right so car like what is stated is rear biased. Want if possible to stay away from proportioning valve so have some questions. Car set up is 305 square slicks, AST 4300 double adjustable shocks, 1200 front, 900 rear springs. Akebono sport brakes. Working now on brake ducts for both front and rear.

Has anyone got a track day pad set up that bias car so it can be ran without ABS? High temp rear low friction, high temp front medium friction?
Was a thinking about putting base brakes on rear, smaller rotor, single piston caliper less braking force, has anyone done this, was it sucessful?

Thanks
