Track prepping the M4

[Caliboy951]

I'm in the process of getting my comp packaged M4 track ready. I've gone with Apex EC-7 rims, Nitto tires, Eibach spings (JRZ's are in the future), APR complate aero package, Dinan rear strut and ball joint stuff (not sure exactly what it is).

Here's my situation, I have a very good friend that has the Z28 and that thing is stupid fast (http://www.motorweek.org/reviews/roa...let_camaro_z28 ) and we have a $500 bet I can beat him at Fontana. It will be a track day that we will race.

Your thoughts and suggestions will be appreciated.

Stupid question, did you do brake pads? Did my first track day with my M4, and left stock pads on. Big mistake.

[slalomfever]

+1 on the pads....OP you may want to upgrade to a better brake fluid as well.

Car looks incredible!! Have you driven aero cars before though? Need to drive them differently through turns.

Doesnt matter what u slap on ur car. Unless both cars will be driven by same person, driver mod will make the biggest difference, esp tracks like auto club speedway. Ive seen guys w vetto z06 run 2:05, yet stock s2ks run under 2:00 w tires. But like others have said, change the brake pads n fluids.

Hopefully he has some experience and isn't going to be "that guy".

You spent all that money to track-prep the car over a 500$ bet ??
You could have at least made it a 10K bet.

looks so mean!

but I think there Is a hole In your roof! is that for down force too?

I kid I kid.

Based on OPs profile pic if it's him on his bike I think he has solid track experience

Thanks for the feedback and I have tracked a car with an aero package and I've done more track days than I can count, mostly 1,000cc sportbikes, Noble M400, Birel/Rotax kart, and raced the WSMC series for several years in 501-650 class. Here's a short clip of myself trying to stay sharp on the wheel so I hopefully wont be "that guy".

In regards to the brake pads, lines and fluids and I've already scheduled them prior to my track day at Bimmerfest.

Here's a cool clip of how fast we go at Fontana on a 1,000cc bike:

OP what wheel setup did you go with? Staggered or square?

Lol, I bought the car with 6,200 miles and and I HATE that sunroof!!!

You won't beat him on the stock suspension, especially after you possibly made things worse by going with aftermarket springs on OEM dampers. Track pads, Castrol SRF, a tune, and a real coilover setup and then you should be good.

What Nitto tires anyway? I would probably go with Michelin PS Cup 2 or maybe Bridgestone RE-71R depending on if you're gonna drive this daily?

If you really want to put the power down out of the corners I'd consider a 305 out back on an 11" wheel

How about some Bucket seats?

[ssuene93]

Nice setup. Will go 305 as others recommended.
