    17x10 et25 brake clearance:

    This made my night!

    How do you like the M3 with 275/40/17 NT01's?

    Where did you end up sourcing the H&R set? I’m trying to find best pricing right now, so I can order and have them drop shipped to FCM. Were lead times bad?
    ECS had a sale on them, so I hoped on it.

    Took ~2 weeks to arrive.

    I'm kind of excited for the extra clearance, as I was having to clean out track goobers getting stuck between my caliper and wheel between sessions:

I used to get 12-15 track days on NT01's on my E30 M3 which makes r-comps relatively affordable (compared to 3 days on RE71r's).

Not going to sell the brembos till I do a track event on these, but on the street they feel pretty indistinguishable from the Brembos. Which makes sense, since they're rigidly mounted brembo calipers with the correct bias/volumes for the chassis, but I still had some fears:

    The front sway bar mount points tore off, so the car's off getting fixed for that (I don't weld well enough to be happy with my work on my car):

    Turns out eibach makes a 6” long, 2.5” ID, 375 lb/in barrel spring, that they don’t offer except through GC... which will let me live my OCD to two decimal places.

    (going with barrel springs up front because I want to have the spring perch above the tire, so I don't need as aggressive wheel offsets, but then need all the travel I can get (as that pretty much limits me to a 6-6.5" long spring).

    Corner weights are a good place to start, though probably not necessary if your car is close to stock. If you can get them, though, you'll be more accurate.

    Jesse
    Yeah, he does a bunch more-- they'll be pressurized and valved to my corner weights and spring rates, bump stop tuning,and I'm having him add his KBO (similar but I believe superior to Ohlin's DFV) and ripple reducer.
