you can see in the vid at 2:30 mark, the rear hop as i'm on power exiting. this was from last weekend at lighting. i don't think i'm loosing that much speed because i stay on the throttle and the front wheels just pull the car forward. it does unsettle the car and makes it track out farther. if it didn't happen, then i can probably carry more speed through the turn and not worry about it tracking out farther from the hop. i also think it has to do with the max lock rear diff, with one rear wheel being off the ground (or low traction). like you get wheel hop on those karts with solid rear axle and no diff. btw, i'm running 275/35/18 A6. i don't notice it with street tires.

I think you are running high spring rates and your car does not like the bumps and throttle input because of it. Less spring probably would dial that out, but then you give up handling on other parts of course. It seemed your car hopped a few more times in video, just not as much as it did at 2:30 point on video. You hit the curb and got back on the throttle which caused the hop. If you didn't hit inside curb car would not have hopped as intensely (I know you need to hit curb to bang that turn right). BTW nice driving through it on that turn (you have ballz). I am quite familiar with that turn actually (hate the long straight then into turn, makes me nervous in my car).
Any real tight turns where you are digging out of hole with throttle will probably bring that hop out, especially if you add any bumps. If you were autoxing your car you would be like us last weekend with driving around the throttle input hop. Are you running a big bar in rear with high rates? If so try the stock bar.

If you don't use breaker bar with 5' extension pole, then your spark plugs aint tight enough. Also use JBweld as thread sealant.

Car still overheats. Not a fan of my car lately and have no patience or $ to deal with it. How about I have a fix Mike's car party at my house. I will BBQ a quality dinner for whoever helps out. Maybe smoke a Pork shoulder or whatever, who is in?? YBRD hint, Cantor hint.
My house is for sale and the past few weekends I have been doing things to try and help the for sale process or I was away Autoxing. So I have not done ish to car for a bit. Oh and then I need a gas tune, my tooner has no time to take care of me right now cause he is selling his house too.
I think I need to just rip the head off car and pop a new HG in and call it a day. Then just put it for sale as well as my truck. I just want to rid myself of them and lease a new car. With some time and $ both vehicles could be great, need to get on that sale already.
So I guess if I fix it maybe but not running it like the last track day. Almost killing myself and 2 other people because of no brake antifreeze/oil effect on tires is no fun and quite distracting actually. It prevented me from getting into the 17's if I remember right at Lightning.

I'm runing 12k/14k with Whiteline front and rear sway bars. The rear is set full soft which I think is just slightly more than stock. I'm also temporarily runing FA 500 which doesn't have the digressive valving to control low speed pump as well. Theyre sending new custom valved 510 shocks with more digressive valve, so we'll see how much of a difference it makes. I don't want to run softer springs because I don't want body role and dive during braking.

Try the stock RSB, bet it gets rid of some of the hop and makes the rear end step out smother, eliminate the twitchy rear end syndrome. If you have the shock settings to dial it out then great, but I do not believe in a big bar when you run high spring rates. All it does is lift the inside wheel then and you loose contact patch of that tire. High spring rates do not suck up bumps in my experience so far. We are going to experiment with the spring rates to see if we can figure out a bumpy surface set up.

the whiteline bar on soft is 42% stiffer than stock. could it be the rebound setting?

12/14 is soft homie. At least for my world. Track usually is a little softer because it's less transition heavy.

Exactly, but stiff for a RR car.... right? So it is relatively similar cause and effect in either RR or Autox, just a different spring and shock valving rate for each use.

All the aftermarket bars on full soft setting are still are alot stiffer than stock.

btw, just purchased a 9-pack insurance policy using my bmwcca membership and saved $198. Total (with their BS fees) came out to $113.88 per event and I'm covered for $19.5k, holla!

Yeah, 12k/14k is still a little on the soft side if you're talking about a dedicated track car, let alone running on A6 tires on track. But i still drive my car on the street, so it needs a little compliance so I don't loose all my teeth fillings.

I was getting wheel hop with all my previous setup also. Ohlins 10k/12k with stock sway bars. Ast 10k/12k with stock sway bars. Ohlins 10k/12k with whiteline front and rear sway bars. And current setup with Fortuneauto 12k/14k with Whiteline sway bars. We'll see what happens when my sponsorssends me the custom valved shocks. Good to know that you guys are still getting wheel hop with your expensive moton. Its more to do with the setup then the equipment you have
