280z4me2 Posted February 4, 2013 Share Posted February 4, 2013 I have the JTR book for my s30 and I just made the setback plates out of 1/4" aluminum. JTR calls for 1/2". I made these because I had just enough 1/4" laying around. Will I run into issues with drive shaft angle being 1/4" off of the drawings? I am running coilovers and figured I would make aluminum spacer for the front suspension assembly to make up the extra 1/4".... Quote Link to comment Share on other sites More sharing options...
jasper Posted February 4, 2013 Share Posted February 4, 2013 I would be concerened about the 1/4" material failing, under load! Quote Link to comment Share on other sites More sharing options...
jaguargt Posted February 4, 2013 Share Posted February 4, 2013 You could use 2 1/4 plates to make one 1/2... even JTR recomends that in some place of the manual... Selvin. Quote Link to comment Share on other sites More sharing options...
280z4me2 Posted February 5, 2013 Author Share Posted February 5, 2013 Is it extremely important that the 3/8 holes are tapped or is there enough room to squeeze in a nut between the plate and engine block? Accidentally stripped out one hole while threading it. Quote Link to comment Share on other sites More sharing options...
jaguargt Posted February 13, 2013 Share Posted February 13, 2013 I think there is enough space to put a nut... Quote Link to comment Share on other sites More sharing options...
Zinpieces Posted February 15, 2013 Share Posted February 15, 2013 (edited) 3/8 - 16 bolt in a 1/4 inch plate only gives you 4 threads. I would not trust it. I'd get some 1/2 inch plate. Try a local machine shop, they charge me 2 dollars a pound for whatever aluminuim scrap I need.
