VAG-COM question - up until today I didn't know that my car had XDS (I'm the second owner so I didn't have any of the marketing materials that explained all the features my car has). A buddy of mine was helping me out with some other VAG-COM stuff and switched off XDS after we discussed it. While it made sense to deactivate it since I have a mechanical LSD (Peloquin) installed, I just want to make sure I haven't done something stupid that may kill me next time on the track!
P.S. What VAG-COM tweaks, if any, have y'all done for track use?
P.P.S. I did go for a quick spirited drive and took a few familiar curves at a pretty good clip and I didn't die so I consider that a win!
I wish I could answer the oil temp question, but I don't have an oil temp sensor installed. It's on my list of things to do, but I'd like to interface with the ECU so I can log it on my lap timer.
I will say that my coolant temps are typically around the 210-215 range, depending on the track and ambient air temps. Water/coolant mix ratio can have a large impact on heat dissipation, so it's something to look at. I run a 2/1 ratio of water to G13 coolant, which still gives me a -18 degree frost protection, but much improved cooling over a 1/1 mix.
I still run stock mounts. I've contemplated running a stiffer bushing for the dogbone, but don't want to introduce NVH since I daily the car. People say it decreases wheel hop. With my LSD, I really don't experience wheel hop though.
Like I mentioned, I would definitely check your water / coolant mixture ratio. That can have a large impact on heat dissipation. Also, what oil are you running?
So I was able to pick up a set of new H&R anti-sway bars (26/24) from a Facebook group. Now I am considering also adding front and rear subframe kits while I am having the anti-sway bars installed. Are there any NVH concerns with the subframe kits? This car is my daily driver and part-time track car so I don't want too harsh of a ride.
There's no good way to check after it's in the car. I guess you could take a sample and send it out somewhere but it's probably a lot less hassle to just drain the coolant, mix your own and fill with the mix that you did yourself. I run mostly water + water wetter for track days. I do add about 20% g13 coolant for it's lubricating properties.
