Default HPDE proofing e90 335i - 03-23-2018, 06:01 AM

I've got a dedicated track car but I would like to use the 335i as a backup so I'm going to lightly prep so it wont limp on me.

It's a 2007 335i and has a JB4 & snow meth kit

I'm thinking this is what I need to do.

map1 with maxcool is going to backend flash any benefit for this? I have MHD already setup if needed
another oil cooler
HPDE pads that can handle advanced run group speeds.

anything else needed? I might get some camber plates too so I do not destroy the tires too quick, will be on street tires, probably > 200 tw too as it is a daily driver

- get rid of the meth kit, they aren't reliable enough for track use. you really dont want to hydrolock the engine because of jammed solenoid or something.

- does your car have an oil cooler? if it does, you will be ok for some light track use at 6/10 pace.

- don't expect to keep up with the advance group's pace with a mostly stock car though. not even full race pads like PFC01 or Cobalt Friction will last very long with the stock brake calipers and rotors.

- M3 suspension bits and some good shocks and springs are a must for this car if you care about handling

I would have a hard time doing 6/10ths

what M3 suspension parts do these cars need, control arms? I run meth in the mini at the track, only way to keep those supercharger temps down

vid from last trackday, that mustang in front of me has 425 hp, i got 200 lol

your e90 is gonna feel like a pig comparing to the mini, at least in stock form.

the front m3 control arms helps a ton with the steering feel. looks like you are pretty comfortable with the mini already, so you will definitely need some camber plates and some good spring/shock/coilover setup as well. stiff or solid rear subframe bushings are definitely something that you will find helpful as well.

there just too much to explain in one post here. i would recommend doing some digging at the e90post suspension and track subforums. lots of good info there.

Yeah you will have to drive it easy. I was never able to track my car hard, the n54 wont handle the temps. 1st lap , 2nd lap, limp mode...
