evildky Posted February 21, 2006 Share Posted February 21, 2006 I just picked up a set of used Outlaw brakes, Looks like the typical set sold by a member here, anyhow the setup is for use on a 240Z hub but I wanted to put it on my 280 hubs as this allows the caliper to mount further away from the wheel, the rotor clears the mounting ears just fine but the calliper will need a small spacer to center it on the rotor, just wondering if a small aluminum spacer would be safe, just enough to make up the difference in hubs, looks like the spacer would need to be 3/8"-1/2" and I kinda figure washers wouldn't be precise enough Quote Link to comment Share on other sites More sharing options...
blueovalz Posted February 21, 2006 Share Posted February 21, 2006 I've used thin spacers (shims if you prefer) on calipers for years. And washers will work fine if you measure them for a matching pair. Quote Link to comment Share on other sites More sharing options...
Mikelly Posted February 21, 2006 Share Posted February 21, 2006 Yup, And Wilwood actually made and sold a kit of "spacers" for a long time, until it was found that the racer types were just going to the hardware store with a caliper and finding the right thickness washers... I sold a brake setup with the Wilwood spacer kit (Used) in a package deal on a brake caliper/ hub/ rotor setup to Morgan Fructchnowhatever his last name is and he swore up and down I'd screwed him over. For an engineer, he sure was slow to understand that SPACERS center the caliper over the rotor when there is a minimal clearance issue as opposed to just machining a complete "bracket" for the caliper. Those kooky ungineers... All book smart and such! Mike Quote Link to comment Share on other sites More sharing options...
JMortensen Posted February 21, 2006 Share Posted February 21, 2006 I wouldn't hesitate to use a piece of aluminum bar stock with holes drilled in it. Washers stacked up to 1/2" just seems a little hokey to me. I can see 1/4" with washers, but get too much beyond that and it just makes sense to use a piece of bar stock to me... IIRC, the 240 hub has a 10mm different offset for the wheel than the 280 hub. I don't know for sure, but you might be able to just run 240 hubs. Did I mention that I have 2 sets of 240 hubs stripped bare with just studs. One set has RX7 studs (longer) and the other has stock studs. Maybe another alternative.

Mikelly Posted February 21, 2006 Share Posted February 21, 2006 Yea, we were talking variences of less than 1/4 inch (And I want to say it was 1/8th inch but this has been 4 years back!). If it got much larger than that, then I'd be suspect of the alignment or stability. But when you're talking a few mm's then I certainly wouldn't sweat it.

evildky Posted February 21, 2006 Author Share Posted February 21, 2006 I was just a bit concerned that by spacing the caliper from the mounting ears I'd be weakening it, I wonder why he didn't just make a caliper spacer for use with the 280 hub instead of a different hub adapter? seems like such a simple solution rather than machine 2 different adapters I kinda wondered if there wern't a good rason for not doing it that way Quote Link to comment Share on other sites More sharing options...
JMortensen Posted February 21, 2006 Share Posted February 21, 2006 With a piece of bar stock between the caliper mount and the caliper everything should be held nice and parallel and won't be able to shift around under heavy loads as much as two long bolts with washers and no connecting structure. Really I think the weak link then is the bolts that you run. Use good bolts and I don't think you'll have a problem. Or buy my hubs. Quote Link to comment Share on other sites More sharing options...
evildky Posted February 21, 2006 Author Share Posted February 21, 2006 I have both 280 and 240 hubs and I even have 280zx hubs should I want a touch more offset I just figured the extra wheel clearance would be handy when swapping between V700's and street tires and drag slicks all on different wheels Quote Link to comment Share on other sites More sharing options...
