Strut tower brace vs. Strut tie bar
I'm still researching what I need for lowering the R56 and it's been recommended to me by someone in the know that it would be good insurance to add some kind of strut reinforcement in case of some hard pothole hits.
Craven offers a strut tower reinforcement

who else sells these?
Question 2, will a strut tie bar be as effective in protecting the strut towers or are they mostly designed for front end rigidity?
Thanks.

which is why i'm asking about the strut tower reinforcement which is designed to protect the strut towers from damaged from road hazards usually not encountered on the track. I don't think there was any mention of chassis flex that i was trying to lessen.
The M7 strut bar is the only one at the monent that will do both jobs.
If you are considering getting camber plates in the future, save your money now. Camber plates will do a more effective job of preventing tower mushrooming.

there is also this one from DDMWorks

What's a good guess as to the cost of this when it is available?

looking a pictures that looks like a conventional strut brace and doesn't have the reinforcements to prevent strut tower mushrooming which is still what i'm wanting to prevent for happening.
The way it attach to the upper strut towers, it does cover up like 50% of the upper tower, so it will definitely help from that standpoint, plus it's tying in both strut towers making everything more rigid....will definitely help and you get the added handling benefits.
I've wondered the same thing. The R56 has been in production for well over a year and many tens of thousands sold. I have not seen even a single case of mushrooming reported in the forums.
The dealers and miniusa knew about the problem when the r56 was being designed....I don't know why they wouldn't strengthen up the area a bit.

well i guess for 'cheap' insurance i ordered the craven version of the reinforcement rings. i thought about the m7 version which also has an option to add a strut bar for not too much more $$ than the craven ( should be available in a couple weeks) but decided on the craven, sometimes simple is better....
nice. I like the Craven too....mainly because of the small detail that they bevel the edge. My square edge of M7 strut bar plates cut through the sheath on my hood release....two M7 bars, two diff cars, same result.
Drewster,
I have Craven's on the way & they should be here this week. Did you have any problems installing yours and is a torque wrench needed for assembly?
Good luck with yours. They look great!

I don't recall the exact torque but I think it is 25 ft.lbs. I would get a torque wrench to be on the safe and it will also be handy if you ever want to check the torque on your wheel lugs.
No, don't make the same mistake I did. You need different torque wrenches for the two applications because the values are too different. The wheel lugs torque at 88 ft-lbs (or 104 ft-lbs for 14mm lugs). The strut towers at 25 ft-lbs is too far down for the same torque wrench to be accurate. I used my wheel torque wrench, set to 25 ft-lbs but it was shearing off the tower bolt before it started clicking (expensive mistake). For 25 ft-lbs, I would get a torque wrench that has a top reading of no more than about 50 ft-lbs.
