Re: [DML] Modified Trailing Arms For 1/2" Bolts

[Martin Gutkowski <martin@xxxxxxxxxxxxxx>]

Well this one slipped the net....

Surely to drill out the trailing arm, you have to remove it from the 
car? That means disconnecting the brake hoses and reconnecting and 
bleeding afterwards, and the rest. It's a lot of effort to go to in 
order to save not a lot of money.

(advert) don't forget I stock geomet coated 12.9's made in the correct 
M12 hex-head just like the originals, $49/pair shipped to North America.

I also am going to try to find fractional Inconel 718's (same material as Toby's bolts). Whatever gets installed will have proper hex heads rather than socket heads (Grade 9 heads are much taller than standard heads, about the same size as a nut). It's easier to find zinc or cadmium plated 1/2" bolts in TAB lengths than 12mm. And they're less expensive too (TAB length Grade 9's are about $7 per bolt).
