There has been much discussion of swapping in various M3/M4 front suspension components onto F2x cars, with various side-effects and compromises (most notably, wheel position in fender).

What I haven't yet seen (and forgive me if I just missed it) is any discussion of what components the M2 uses, if different, and whether they would be a better (or at least, alternative) solution that might have less side-effects.

Perhaps those parts simply aren't available separately yet, although that seems unlikely.

Perhaps also it uses the very same parts, and avoids the aesthetic problems another way (e.g. by having a differently shaped fender). Is the M2 wheelbase the same as an F22/23?

Thoughts?

They are the same part for the M2 and M3/M4

So what other parts of the whole front wheel/suspension assembly are still different on an M2?

For example, why do the Tension Struts need those third-party spacers? Does the M2 body have a different mounting point?

I'm not trying to be awkward. It just seems to me that if all the M2 parts are available, the whole thing is a solved problem...

you can check realoem.com and compare each part#

LCA's and TS i believe are the same

[simoneves]

OK, so yes, the entire front suspension assembly is the same between the M2 and the M3/M4, including the mounting frame. The assembly on the F22 is all different, including the shape of the frame and how the LCA and TS mount to it. The spacers must therefore be to account for the different style of mounting points on the F22 and M2/3/4 frame.

The remaining question is how the *positions* of the LCA and TS chassis mounts differ between the two, relative to each other and to the strut. But I guess only I care...

Buy an m2, will solve the problem.....

The reasons for the spacers have been covered in the other post.

Will it make you happy?

Thank you. To get the same alignment as stock. The reason they're required at all is because the subframe and hence the mounting points are different so they're not really just a drop-in replacement.

That's all I needed to know. I'll crawl back under my rock now.

damn... you guys are rough.... my intention was just answering the question not owning anything lol

if you just add TS you will toe out,

if you just add LCA you will toe in

Both you still need an alignment, Just removing the part and replacing with same you would still need an alignment per BMW manual.

By alignment I really meant geometry. I understand that an alignment would be essential. The point I'm try to make is that the reason the spacers are required is to place the inboard ends of the TS's at the same relative position to the rest of the suspension components as they would be in the different mounting points on the different subframe of an M2/3/4. Question answered. Thread closed. Thanks.

So if you do both at the same time, it appears that the alignment isn't wildly off, correct?

drive slowly, directly to alignment shop: it'll be way too toed-in

Yeah will still be toe in, not as much as just Lcas, but way more than spec.

[jmwilson125]

Does anyone sell a kit with all pieces including spacers?

[rwalker]

not that I know of, but I bet Harold at HPA could be persuaded to do so
