Hello

So I don't if some of you saw me on the F8X forums but I have been there for quite some time and the M4 has always been the car I want for such a long time.

But the market it still high priced even for used cars.

So my other bet would be to get a new 435i.

Any mods I should do or your recommend to make it more like a M4.

I understand it won't never be a M4, but anything that can get it closer to it is great.

Physical or performance mods.

Thanks

By the time you mod properly to get it to perform more or less like an M4 with suspension, brakes, cooling, tune, etc. you are going to be pretty close to used M4 territory if not over.
I have seen used M4's with little options for roughly $75K cdn. That is not to far from a new loaded 435.

Here's the proper DIY...

NOS will bring a F3x to a F8x. The joke's on BMW for hiring all these clown engineers to do the maths and ergin33ring for ///M.

A new speced like I like 435i is 63k. Used M4s right now are 75K CAD.

Any idea if the price will drop in the upcoming year, or it will be next year?

75k is just a bit to much. I would be much more comfortable with 70-65.
I can always just save up more for a bigger down payment, thus the price will go down to by the time I get it.

It's not just the performance.

It's just the goodies, interior, looks of the M4.

I guess I will just wait for it to become cheaper.

[mike@x-ph.com]

Doing this type of conversion will cost you more money than getting a F8x

I would get a 435 + FBO mods and KW coilovers

Yeah it probably will ha ha.

I think I will just go with a used Audi RS5. Love both M4 and RS5 and if when I'm ready to buy the M4 is still to expensive, the RS5 will be there.

Check the wheel wells of the RS5 for chipping flaking paint.

Thanks for the heads up.

[nicknaz]

You could swap tires, and get full coilovers and that will be fun

Personally, I think a better answer is an older M car. If euro delivery wasn't on the table, I would have gotten an E46 or Z4M modded the heck out if it. Way cheaper than 435

There's no way to make 435i become a M4 simply because you cannot change the chassis, which is the most important part of the car IMO. You can change suspension, brakes, add a tune, etc. to make a 435i run faster than a M4, but the driving dynamic will not be the same as the M4, and you will exceed the cost of a M4.

If you want a M4, get a M4. It just doesn't make sense to get a 435i and mod the sh!t out of it to make it become something it is not.

It's not about making it "something it's not"...it's about making it something it should be...

I highly recommend coding your car to change your Active Sound Design setting to the S55 engine and F80 chasis. It sounds like you are driving an M4 afterwards. I'm sure it's faster, too.

You mean like this...? . .

It's pretty easy in just a few short modifications , your car will be just like an M car.

First, car needs a diet. Need to lose about 200 pounds. not sure how that's going happen.

Next, we at least an extra 100 hp. JB4 + DP + E85 + maximum boost should do the trick.

Breaks , about equivalent. Rotors are slightly smaller but smaller but the breaking surface is the same.

Suspension , not sure how this will get addressed, we'll need some different Suspension, bigger role bars, super springs, etc. I'm sure there's something on the aftermarket.

Stiffness, chassis needs to be a lot stiffer, maybe some extra braces?

That should do it

[mrmoua2u]

save your money and just get the M4, no matter how much you spend to upgrade your 435, it will and never will be a M4. Do it right and you will have no regrets, trust me, I know coming from a F30 to a M4.

If it were that easy, then everyone would be as fast as M3s on the track.

... you can do all those mods and you still won't be able to be as fast as an M3 (for as long as it can - endurance).

by the time you option, retrofit everything on the 435i and go fbo u still won't out run a jb4 m4 even stock + tune.

RedBMS channel has a vid of pure turbo m235i vs jb4 m4. Even that choked up top.

Handling wise I was able to equal my M4 minimum speed through a series of corners but I cheated with wider and sticker P Zero Corsa 255 & 285 aggressive cambers on lighter 20lbs 19" with m3/m4 front and rear arms vs PSS 255 & 275 done on w "private test track" call Sunset Blvd between Beverly Dr and the 405.

Point is u can throw money at it now or later. But you still won't have an M car. As the car is more then the sum of its parts. S55>N55 any day, plus F3x doesn't have the torsional rigidity. If you want an M car, you want one. They have different chassis code this gen for a reason. To be clear I have a 14' 320i daily FBO 300+ wheel and 15' M4 that I took over a high down lease with low residual from a buddy to buy it. (correction more like I bully him into it once I drove it) You look at it, sit in it and everything look the same. But it's so so not lol.

Your buying a package, not just just stats of a sheet. If you haven't driven one. drive them back to back.

If you just want the speed not so much the handling balance. May I suggest a 14' S5 Cab? White on Red APR Stage 2 500+ HP, FI exhaust, KW V3, with Vossen CV5. Got bags too actually, no more "stance lyfe" for me.

It will also be tough if not impossible to replicate how the F8x rear limited slip diff works in a F3x car. It's not just a simple/dumb clutch based LSD. My understanding is that it's integrated into the DSC system.

the Quaife Mechanical LSD will solve the problem for $1,500 probably more effective too. Haven't tracked yet so I'm not sure but I definitely don't like them on the street. I do run -2.5 camber (prefer traction during and out of a corner) on both cars so I'm not expecting miracles in a straight line. But Jesus it's hilarious how easily they spin.

That's incorrect.

Quaife (Torsen) LSD doesn't hold a candle to the rear diff in the M3.

The M3's rear differential is an electrically controlled/actuated clutch based limited slip differential. That means it's tied into the entire vehicle's DSC system and provide variable lock. It's a completely integrated solution.

While the Quaife LSD is not bad and can hold power/torque, it has one major flaw which is that it will act as an open diff if just one wheel lifts.
