newbee needs advice of what would you do

M235i 2016 27K miles

Was thinking of buying M2 but the $$$$$ is crazy and its probably to much car for me.

I need advice of exactly what you have done or what I could do for mods for suspension.

I basically know nothing....A Michigan independent mech would also be helpful.
or a BMW dealer you know would do it right.

Looking for a bit more from this car.

Any advice would be appreciated.

A quality coilover kit with camber plates is generally a good start to improving handling.

A limited slip differential and some solid rear subframe bushings will go a long ways towards allowing you to use all that power you've got. The diff is the perfect complement to the negative camber the camber plates will allow you to run.

Bimrs.org (https://www.bimrs.org/) has a listing of independents with dealership-level expertise; alternatively, a qualified race shop that knows BMWs will be able to advise you and do the work.

You can see the route I chose in my build thread: https://www.2addicts.com/forums/show....php?t=1532418. The cost of all that will be overkill for most owners, but if I'd bought an M2 I would still have bought a coilover kit with camber plates and converted from wheel bolts to studs. For a straight street car, I would have skipped the wheels and tires; the pads, fluid, and lines; and the harnesses and tow straps.

Thank you. There are a number of ways to go about improving the performance of our cars, yet the fundamentals do not change. Underneath it all sit basic physics.

Thanks for the,responses.
If I go step,at,a time.
And start with m performance LSD
Will I see improvements or will it be not much until I add more ?
Would I,ever,just do lsd and stop?
Some one suggested lower control arms off a m car ?
This is where I am very new to this.
Everyone raves about the LSD but is that a good start that may be enough or does it continue to add parts until I have a ton of money into a car that may want to trade up eventually

I stopped at the LSD. Although I do track the car twice a year, and do an occasional auto-x, this is my daily driver. Any other mods will take away from the generally nice comfortable street handling of this car. They might make the car 'better' in some way, but it will subtract from comfort.

I also aim to keep the car in F Street class for auto-x. The LSD is the only mod allowed. This also has the major side benefit of keeping me from spending a lot of money on suspension parts for the car. Which is more money for track time, tires, and other fun bits.

I would start with the M4/2 LCAs they are about $400.... the LSD would be like $1500

LSD won't improve handling but will give you more control/traction on turns or where there is limited traction

Ok

I appreciate all inputs...that is how I am going to learn and understand what I am about to do.
Starting with the control arms is the most cost effective start.
Looking for more road hugging when driving with some spirit
The LSD is $3000 and everyone loves it so they say but is it something I will love on my street driving/ F1 in my mind kind of driving.

Keep any comments coming you won’t hurt my feelings in any way....I am old and above that.

Thank you

235 is pretty well dialed in for speed on the road.
Even relatively maniacal driving on the road won’t eat tire shoulder in a day. You may go through tires quicker but that’s to be expected.
Also on the road you can’t be too stiff and you can’t be too sensitive.

I’ve been really curious to compare 18-inch and 19-inch tires on the 235. I think that would be an awesome upgrade if the roads in your area can handle it...as a daily driver I stay away from 19-inch.

If u want a bit more from the car - get above 4000 rpm put suspension in SPORT and think if you really need any upgrades.

I found no noticeable difference in ride quality between 18s and 19s.

I'd suggest the opposite, trying 17's with performance tires, and at least another half inch of width to fully support the tires - the reduced weight will help more than the stiffer sidewall on 19's (and those 19s will be ADDING unsprung weight - something I find mine is very sensitive to). I'm finding the Bridestone s007's to be an excellent step up from the Conti's, much better dry traction and shoulder wear-resistance with almost no reduction in wet-handling.

And this is very true: "on the road you can’t be too stiff and you can’t be too sensitive. " If you go too stiff, you'll lose compliance and be bouncing along rather than holding the road. Don't buy the magazine hype about 'flat cornering' being the ultimate goal; a tire has zero grip the moment it leaves the pavement. Street driving will seldom put the car up against its ultimate limits, so you want to focus upon driveability and consistency rather than things that raise ultimate limits a few points.

My concern with 17-inch is the second rebound after a snap oversteer...it's just that one time...but I'm not tracking my car I don't really know if that's a 'thing' to worry about.

17 inch wheels

I'm under the impression that most 17 wheels won't fit with the M sport brakes?

quite a few 17 inch wheels fit, it's a popular size for snow tires on the M-brakes fitted cars.

I wonder if the close fitment thought effects brake cooling.

I don't know about most, but Tire Rack shows four manufacturers with seven different 17" wheels that fit the M-Sport brakes on the M240i: https://www.tirerack.com/wheels/resu...taggered+Tires. The BBS SR/SX are popular wheels for winter tires on our cars; I run a set of SRs on my car in the winter.

There are bound to be others that will fit, too. For example, Bimmerworld has three forged 17" wheels that fit over the M-Sport Brakes: https://www.bimmerworld.com/Wheels-T...ameter:17$2522.

Spend your money as you will, but your buying one of the best cars in the world. There is no way you can legally use even what the car can do stock on the street. You said your a newbie... other than maybe better brakes to handle heat better and doing the mod to keep the exhaust valve open... go see what she can do and spend you money on the things that will make YOU a better driver. Most exhaust systems kill mid-range power especially without reprogramming the computer check with others who've made the mod and to how the powerband changed..... The low to mid range torque on this car is what makes it so much faster than the 1 series and reminds me very much of the power delivery of my old RC-51 and my Superhawk both torquey V-twins.
