Modern Motorsports Ltd Posted December 3, 2002 Share Posted December 3, 2002 Originally posted by ToplessZ:Thanks for the info Ross. I think you saying do the 300zx conversion to the 5 lug discs and then with an adaptor id be able to bolt on these rims. Also I noticed that the rims im looking at have a +45 mm offset. What kind of cost am I looking at min/max to do this conversion. Thanks for your help. Jared, I've been wrapped up in tasks lately and not enjoying hybridz as regularly as I'd like by any means. A cheap front 5lug brake setup is the 4runner vented caliper setup. You use 88-91 vented 4runner calipers and early model 300ZX front 5lug rotors with custom rotor spacers. I have the rotor spacers in stock, even one set anodized (clear) at present for $150 including all rotor/spacer hardware. I've got a parts store set of new front 4x4 pads that came in a loaded caliper you can have cheap (new pads/customer opted for my KVR's which I also have in stock at $40/set). You can source used or new rotors/calipers locally or I can supply you with new but you mentioned a skinny budget. The new 5lug hubs add ~25mm offset to your present OEM hub offset. So with 25 used up, and 45 on the wheels you want....that leaves ~20mm for the bolt on adaptor, if you maintain your centerline, which is 0.78" and falls within a thickness I can make bolt on wheel adaptors (likely requires shaving your wheel studs so they don't protrude from the ~3/4"-1" thick bolt on wheel adaptor, unless the BMW wheels have recesses they can fit into which many do have). A set of 4 of those adaptors in a 1" or less thickness would run $210 max plus shipping. If you need thicker units out back the price would change somewhat. You'd also require 5lug front hubs from an 84-89 300ZX with bolt on rotors (find a good set with good rotors and you're smilling:). As well you'd require prepped 5lug rear stub axles, they're $110 fully prepped with all work done by a machinist with fixtures to ensure properly : removed bearings, welded eyelets, aligned new wheel stud holes, aligned press in of new studs and rear seal plate mod. Cost of $110 including all service and ARP studs, you supply your stub axles or buy a set (I have some already prepped for exchange with cores sent). The 2 pc. adaptors others mentioned are certainly an option. I have no experience with them. One advantage of going to the nissan 5x4.5 base pattern is if you tire of your 5x4.75 or want an alternate track/drag setup you can then easily swap to other rims on the 5x4.5 pattern. Even if only for wknd events as spacers can be quite flexible. I know of several hybridZ's that will swap to race rims of greater width and diffeernt offset using a 2nd spacer set for wknd events.....takes only minutes. Just an option, might leave you more flexible longterm. Feel free to email me with any q's at all that you have. I rarely get time to go into hybridz lately as I'm progressing new packages and making sure customers needs are met. But as you see most all of your q's will get answered here or directed to someone how can. One helluva group that's helped me develop the parts I now have to share. PS thanks for the web feedback:) Just revamped today/yesterday! Quote Link to comment Share on other sites More sharing options...
gene_w Posted December 3, 2002 Share Posted December 3, 2002 Ross, How thick does the spacer need to be to use the 300zx hubs & rotors with 4runner calipers? Do any other modifications need to be made for this setup? I have been planning on using 280zx calipers as per Terry Oxandale's writeup on zhome.com, but it requires me to grind off 1/8" from the outer edge of the rotor. Is this modification necessary with the 4runner caliper? Thanks Gene Quote Link to comment Share on other sites More sharing options...
PaulR Posted December 3, 2002 Share Posted December 3, 2002 Originally posted by Tomahawk Z:Paul what is the backspace on those wheels? The 17x10.5 wheels are 28mm offset and have a 6.8" backspace.The 17x9 wheels are 24mm offset and have 5.9" backspace. In the front, I am using the 300ZX hubs ('86) and rotor spacer that Ross describes. I am not using a wheel spacer in the front. On the rear I re-drilled for 5 lugs and use a 1.25" bolt-on spacer. I got my wheels from www.performancewheeloutlet.com , but there are lots of other aftermarket suppliers for this style wheel. Performance Wheel doesn't get high marks from me for customer support, but in the end, everything worked out. Pick up one of the Mustang enthusiast magazines next time you're at the grocery store and thumb thru it if you what to see who else makes them.

Guest Anonymous Posted December 4, 2002 Share Posted December 4, 2002 This wheel switching is more complicated than stroking an engine Thanx Paul for the back space Data. Jared must be on sabbatical leave. With Ross C and your input ,there should be enuf info when he obtains the back space on the wheels he wants to see what he needs to do for modifications. According to my math around 5 1/2 inch allowable maximum backspace on a rear wheel and 5 inch allowable maximum backspace on a frontwheel with no modifactaions save coilovers?

Mudge Posted December 6, 2002 Share Posted December 6, 2002 Originally posted by Clifton:You can get 4 to 5 lug adapters but they add 2". http://www.truckn-store.com/product_list.asp?id=466 Looks like they can maybe do custom, but they dont have any 114.3mm to other bolt patern listed other than (as I found) a 5 lug in 114.3, being a 4x110mm to 5x114.3 which does about zero good. Is anyone running old 4 lugger Mustang wheels with spacers? Mustang 4 luggers are 4.25" Quote Link to comment Share on other sites More sharing options...
