Hey All... and don't give me grief for an EOS. I'm married with kids and love convertibles and we had not had one for 8 years, and IMO the EOS could not be beat for the money. Yes it definitely is a female car but I'm working on fixin that!
I did a HPDE a month ago and had a BLAST!! You will love it! I was totally stock except for Stage 1. The EOS did well, much better than I was expecting. The independent rear suspension helps and it was surprisingly neutral, I was expecting more push, based on my prior experience with VW's and FWD cars.
Another old fart like myself was there with a 08 GTI, totally stock. He boiled his brake fluid. Now we were in TX and it was in the low 90's so keep that in mind. I've been working with a local Tuner shop and the guy there just came from working over a year at the Tuner shop at the track. He said by far the most common problem at HPDE events is brake issues, in particular boiling the brake fluid. This is caused by 2 common factors, low grade brake fluid and rubber brake lines expanding and allowing moisture into the brake fluid and thereby lowering the boiling point of the brake fluid.
So here is my .02 cents. The only thing I would consider BEFORE the 1st time is putting in a high quality racing brake fluid, like Motul RBF 600. Once at the track you'll learn A LOT about what your car can and can't do and there will be many people there who you can talk to get an idea of what makes sense.
What you'll probably want to do after the 1st time assuming you are going back?
Good Tires
Sway Bars
Brakes - race pads, possibly stainless steel brake lines
At least a Stage 1 chip, best bang for the buck, period!
Here is what I'm doing:
VF Engineering Air Intake
Engine Torque Arm Insert (also called dogbone)
EBC Yellowstuff Brake pads (you'll need the tool for the rear brake caliper)
Front and Rear Sway Bars - Neuspeed (I'm going to give this a go, I definitely will do the rear, the front is pretty involved but I think I can handle it)
MSW Type 14 Wheels and Bridgestone Potenza RE-01R tires (changed my mind and am going with the Dunlop Direzza Sport Z1 Star Spec) I am tempted to get the Toyo R888 tire(and am still thinking about it) but it is expensive and you can get the your tires balanced and rotated for free at Tirerack if you buy wheels and tires. Tirerack does NOT sell Toyo. Toyo for my size runs around $210 per tire, the RE-01R $150 and the Z1 around $115. The Toyo is a pure track tire, though it is street legal.
Tuner Shop Install
APR Downpipe (APR is having a sale again through Oct 18th, looks like the DP should be 15% off)
APR Stage II ECU upgrade
Wheel alignment - change the camber for better track performance
Stainless Steel Brake lines and change brake fluid and bleed (I plan on swapping the brakes pads just for the track)
That is ALL i will do with the EOS. If I get serious and I'm 99% sure I will then I will get a different car for the track, frankly what I really want to do is race.
ESP - I turned it off. I feel like it interferes and does masks mistakes.
EZ Up - Yes, Yes, and Yes!
