Bolt Pattern Change-something new?


Guest Anonymous

I was told that it is possible to REPLACE the bolt pattern on my existing 4-bolt drums and discs. Something to do with removing the old bolts, weld em up, then drill new ones!

Any ideas? I'd really like to put some old Torque Thrusters on my car!

You can get 5 on 4.5 pretty easily but I'm not sure that's th epattern you'd need. Also don't forget about backspacing - before you go to all this trouble find out if you can get the correct spacing for your car. I just found out today that the wheels I've been admiring for months are no longer available and am MOST unhappy about it....

Have you gone to a 5 bolt pattern? it sure seems all the wheels I like only come in 5. I REALLY don't like the idea of spacers/adapters, I do like to push the limits sometimes and it seems they would be a weak link.

If I don't solve this soon I'll probably just get another set of Cenerlines and get on with my life!

YES, I've gone to 5lug and am installinginstalled 4wheel disk brakes from MikeSCCA.

 

To do this you must replace the front hubs with 300ZX hubs. I drilled mine out for bigger ARP studs. 300Z rotors work up there but I'm not sure on the specifics of calipers for that. I went with 12inch rotors and bilet calipers instead. I DID have a setup using Toyota calipers for that come to think of it - not sure on the rotor. MikeSCCA can help you there with all of that or search the archives.

 

For the rear - you must use only ONE of the existing lug holes. Th erest must be drilled. I don't recall the bit size but if you search the archives you'll find it and a WEB page detailing how to do it. I'm using 300ZX Turbo rotors and custom brackets with billet 4 piston Outlaws and Wilwood spotz for an E-brake. This part isn't yet done but Mike should have the brake bracket coming to me "soon". (right Mike?)

 

You can also use 200SX calipers (iron and ugly) or possibly Pulsar NX brakes. This months Sport Compact car shows the same 200SX brakes that we use being tossed for NX brakes so I ASSume this would work - anyone else notice that article? The bracket for these is either weld-on tabs or a bolt-on that wouldbe custom. Mike and others are working on a CNC bracket that should work for this and could use 280ZX calipers too I think. Not sure if the 280 stuff canbe used with 5lug or not.

 

Note: I'm NOT the expert and I'm NOT doing this on the cheap for my car. You CAN do it cheaper and I'm going to end up having more brake than I need for my car. I think I'll live with that icon_smile.gif

http://216.254.117.47/ is a link to my server. In the photo gallery you'll see the brake pics. Not great shots I'm afraid but Mikelly has some on his photo site and MikeSCCA has some on fonebooth.com too. The archives have a link for doing this more cheaply but to answer your question, yeah it CAN be done! Wheel selection skyrockets but you may need spacers to get everything perfect - with the ARP studs stud strength isn't as big an issue. +20mm has been used on all 4 corners by another member but that probably won't work with the 300ZX hubs. I think about +38mm with those hubs is best. I'm trying to find good wheels myself right now so stay tuned and I'll let everyone know what backspace seems to work best with the 300ZX hubs etc.

 

Okay, I'll shut-up now...
