Thought I would share this experience in case anyone comes across this problem with strut braces and the Vorsteiner GTR hood.
I had the Strong Strut front strut tower brace on my M5 until earlier today. I really liked the Strong Strut, it is a wonderful piece but I was having a slight issue with clearance...the top side of it was just barely rubbing or touching the bottom side of my new GTR hood. Yikes!
I got REALLY lucky and there was no damage since it was literally only touching enough to slightly scuff the paint...and I noticed the situation and put self stick temporary pads there as a buffer.
I think the Strong Strut clearance was not an issue with my stock hood because it was snug against the padding insulation on the underneath of the hood. My new GTR hood is carbon fiber underneath with no insulation material like the stock hood.
The Strong Strut could not be adjusted to my satisfaction in terms of clearance...so, I hated to see it go, but it has been replaced with a new Dinan brace which sits just a slight bit lower (maybe about 1/8" or 1/4") so it clears with no rubbing...also, the Dinan brace is brushed aluminum and carbon fiber which everyone knows is right up my alley...and matches the rest of the look in the engine bay.
The beast feels even tighter if anything with the new brace. I had great service today from Ron up at Performing Imports in Alpharetta, GA. He installed the brace himself to his exact standards and was very friendly and helpful as usual.
Oh, and before anyone asks, the Strong Strut brace has already been sold to a local friend and fellow board member.
