Intercooler recommendations for tracking

I've done 5 track days in stock form except for pads, fluid and 265 squared. I have a good feel for the car and am ready to start working on the suspension and cooling. Any recommendations for intercoolers? I'm happy with the stock power and don't plan to upgrade except for a catted downpipe.
Also, I'm torn between club sports and olhins. Does anyone have any hard data on lap times?
Thanks!

I've heard that the club sports are not street friendly at all. I've seen many used sets for sale. Although I'm sure they are fast. Something like the Ohlins could maybe get close, especially if you utilize some stiffer sways to compensate for the softer street coil over offerings. I'm running the H&R adjustable sways front and rear with adjustable links, it's amazing what a difference full soft or stiff on the front bar does to the balance, turn in feels lightning quick with a hard set that holds through the corner.

The car feels more predictable on stuff out front but I think a forward balance would be faster. I'm not on a square setup though. I have 265/35 re11's up front with 285 rears. So you probably want a little push than I have dialed in.

For the intercooler I would just research the best cores and their density/pressure drop. There are a lot of cheaper options out there that utilize the same core as more expensive offerings. The difference being they don't mark them up like other companies. I like a lot of the step intercoolers.

What’s the reason for the inter cooler if not adding other power upgrades? I’ve used the car on track in high heat and it seemed fine.

Doesn't it feel like it's pulling power in the heat?

Have KW 3 Way Clubsports for sale (listed in classifieds). Can't say anything about the Ohlins. But pretty sure I have most of the fastest Laps at the SoCal tracks on them.

Curious as to why you're selling. Had the v3's on my evo and loved them.

I added a Dinan intercooler a week after I purchased my M2. The primary reason was to ensure long-term reliability and power delivery at the race track. I haven't added gauges yet (or the bimmercode app), but I'd expect the intake air temps begin to rise dramatically when using full boost, on-track, for extended periods. The stock air/air intercooler appears very under-sized.

I'll be on-track in a week or so and I'll let you know. The Dinan unit is built very well (bar/plate/fit/finish) and is just plain huge (and appears well-designed w/the twin cores).

There used to be a very significant hesitation/power drop above 6500rpm in my car when tracking on hot days. The power drop is gone after installing the Dinan IC.

Nice! My guess is a good intercooler like this will keep the IAT's close to ambient w/ minimal pressure drop

We're waiting for the track update.
