No even close. You'll be shocked at the difference in front end grip plus the MUCH meatier look. They are much wider than the 225s.

Ooohhh 245/35 would be so nice. I didn't know a 245 would work in the front! Do you have any pics?

Indeed it would. I'm in agreement with XutvJet that the increase in grip will transform your car's front-end handling.

VRSF 5" intercooler installed today! Started at 10:00 am and ended up finishing around 1:30 pm. Not terribly difficult. Just a lot of screws/bolts to remove. We had trouble with the cold side getting caught on the charge pipe spring clip.

Gave her a good wash afterwards and then flashed MHD Stage 2+ until Bob dyno tunes it next week.

Got the car dialed-in by Bob at Stage Fab today. Results are 377 WHP / 438 WTQ

Not bad, is this an OTS tune? Numbers seem consistent with off-shelf tunes for MHD/BM3 but would be a 20-30whp lower than most custom tunes I've seen, with equal mods.

Also, what altitude are you at?

No, custom tune by Bob. Elevation in Youngsville is 462'

Agree that it seems a little low

The numbers look very solid. A lot of shops/tuners report their Dynojet numbers in STD and not SAE like your plot shows. SAE is a more realistic calculation.

If you want to gain some power, simply convert to STD (~+3%). So that means using the STD calc, your car is making ~390whp and ~455wtq. That's quite stout, especially on the torque side.

Ah that's right. Good point! Forgot about the different calculation variants. 👍

Hell yea, that looks great. Are you lowered or stock springs?

Thanks. Dinan springs with 1/4" lift spacers in the back only. I really wanted the rear springs because they are 30% stiffer and these car's tend to be bouncy in the rear with the stock springs. The Dinan's lowered the rear ~1" (nearly 1.5" without the spacer) and better matched the stock spring rate of the front. I have no desire to add the Dinan's to the front because I feel the front axle spring rates are good, the wheel gap is fine in the front (~1"), and the Dinan front springs are only about 8% stiffer. The chassis dynamics feel so much better with the Dinan springs out back. It was really surprising to me the difference.

Very cool. Love the look. I've seen other 2ers dropped on springs and the front always looks too low imo. Where did you purchase the 1/4" lift spacers? And did you have to buy the front/rear spring set or did you find rear springs separate?

Agreed. I don't like the slammed front end look at all. With the right offset and wider tires in the front which push the shoulders more flush with the wheel arch, it makes the front appear visually lower. I prefer the classic BMW stance which is the rear appearing visually lower than the front. My model for this look was the 1M. Most every sports car out there has this reversed rake look. The obvious reason being that the front arches are bigger since the front wheels need room to turn at full suspension travel.

The spacers are available from Dinan and they are hilariously expensive for a piece of solid and round 5mm thick white plastic ($100). But since they fit perfectly and raise the rear a much needed 1/4"+ inch, I said screw it and bought them. The improved spring rate makes a big difference in perceived chassis control from the seat of the pants. The chassis feels way more controlled and a bit more taunt out back and much of rear axle's secondary motions reduced significantly. I'm not sure if they actually improved handling or not because I don't track the car.

You do have to buy the springs as a set. It's expensive for just two springs ($450 with the spacers) but they are quality pieces, improve the look, and improve the chassis. It was worth it for me.

It feels night/day better! Accelerating from a standstill is a lot smoother, accelerating while in 3rd-5th gear is amazing -- no stuttering or choppiness, and the car feels nimbler in the frontend.

Not to mention I can now swing the back end out on turns and light up the tires a bit

Best $150 I've spent on the car so far!

Glad I could help! Did you ever try changing out your transfer case fluid? I'm curious what the difference is between your 0-60 time with xDrive off vs xDrive on

Not yet! I need to clock some new 0-60 runs in RWD mode soon. I've been wanting to see how they are after my new tune

[whoismorggan]

3.69 0-60 run today! Pretty impressed

Updated my navigation with the 2020 maps. Found a torrent link on here and partitioned a 1TB drive I had lying around. Only problem was the torrent did not include a .nmf file that I had to add manually.

Finally received the alcantara steering wheel I ordered from Spain on eBay. Tri-color stitching with red indicator stripe and it retains the heating function!

Installation was a b$@%h. Couldn't get the airbag released for an hour or so, and then I had to cut away some of the material so the trim would fit flush. THEN, as I was removing both paddles the wires stripped out from their connectors.

So, will be running paddle-less until I can get new ones ordered

But, overall the steering wheel looks and feels AMAZING. So happy with how it turned out.
