Slon Workshop E46 M3 Carbon Front Triangulating Reinforcement Kit

[Advorsor]

My quick thoughts:

(I've installed both the front brace and rear wall)

*Disclaimer* = the others who have done these upgrades (also posting in here), are likely more sophisticated than I am in terms of determining any changes in drive experience.

That said, to consolidate my impressions so far, "slop" in the chassis feels somewhere between moderately reduced - to - meaningfully reduced. I don't want to go on record and say the enhancements are 100% on the meaningful side of the spectrum because that probably sounds like I am justifying the high price tag for these items.

To phrase in a possibly different way, the car certainly inspires additional confidence/performance with respect to driving it harder in more frequent situations..

Thank you for your Honest review

One thing that I haven't seen mentioned. How much, if at all, does this brace reduce clearance to the engine underneath. 1. Compared to the stock strut brace in the front and 2. under the cabin filter in th eback. Does the new modified cabin filter housing provide clearance for the rear of the brace or is the brace below where the OE carbon filter housing would be?

Curious if this is installed does it meaningfully reduce clearance for an engine swapped car with an intake on top of the engine.

Finally had a chance to get my car reassembled, with the rear wall installed. Hoping to be able to take her for a spin tonight!

Upholstry work is very much not my forte, but it's the trunk, which I've always looked at as the business end of the the car, that doesn't need to look immaculate.



Stupidly, I didn't think to take a picture from the front, and now the child seat is installed... so I can't.

While those rods probably worked better, Obioban use of a s85 v10 head is such a flex.

Not sure what people are talking about when they say the rear plate isn't as noticeable as the front brace-- to me, it's just as impactful to the driving experience, in all the same ways! It also has an unexpected side benefit, that I'm getting notably less sound transmitted from the trunk to the cabin. That may sound like stating the obvious, since I literally put a wall between them, but enough sound deadening was removed to install it that I expected it to go the other way. Related: I'm pretty sure this is actually a net weight removing mod, once you factor in the sound deadening that must be removed to install it.

Without a doubt, heinzboehmer wins best install setup:

If "best" means "most overcomplicated", then I agree!

I'd miss the passthrough where I stuff my wheels, jack, and tools when heading to the track.

I did consider that a bunch before embarking on this. That said-- I always put all 4 track tires in the seat, and my bins/jack/chair in the trunk. So, I don't think it's going to impact that.

... and outside of track use, where the child seat comes out, I haven't actually been able to fold my back seats down for 4.5 years anyway, because of the kid (baby/child seat).

For the first 8 years I owned my M3, it was my only car. In that era I needed the fold through, so this wouldn't have been viable. Since I've had other cars to use for more practical needs, I don't really feel like this is a compromise.

What do you mean "if"??

I find it amusing that all of us purchased this rear wall 2 years ago during the group buy, but somehow everyone is simultaneously getting around to installing it now.

Yeah it's funny how that ended up working out.

Hey Slavik, awesome. Can't wait to hear your impressions of it and hopefully see it in person someday.
