Kurai Posted February 3, 2010 Share Posted February 3, 2010 Ok I have been searching around and just cant seem to find the exact answer that im looking for...... I'm looking at these rims http://www.shop4wheel.com/product_13613_103261.html What id like to do is get a 18x8.5 front, 18x9.5 rear. I will be running a 1" lowering spring and using the stock hub, also will be running the flares. So with that info what size spacer will i need to make it all work? Will I also need extended studs? What size tire can I run and get the most meat (tire) outta the deal without rubbing? Also this will be on a targeted 500+whp 1JZ powered S30. Thx in advance offsets drive me crazy.

deja Posted February 4, 2010 Share Posted February 4, 2010 http://www.bigcustomwheels.com/rt_specs.jsp That 35 offset is going to put that wheel 1.4" inside of 0 offset. That will probably hit the strut perch without using spacers. You can use this link to see what size tires will give you width and height and then do some measuring to see if you have room in your fenders.

Oh and looking around it seems the largest spacer I found on one site is a 25mm. Is there a place that makes them to order that is well known in the Z community? Or will 25mm be ok...and I have read spacers are safe for the most part but is running one that big ok?!? Quote Link to comment Share on other sites More sharing options...
deja Posted February 4, 2010 Share Posted February 4, 2010 I am running a 17x7 40 offset wheel with 1.5" wheel adapters. I'm running an LT1 but no where near you 500 RWHP you're talking about. Safety is a debatable issue but IMHO if you do proper maintenance like checking torque on the adapters before racing you should be fine. Just my opinion based on what I have read, no real data to back that up. 25mm is only .98". That gets you closer and might be enough. Search for wheel adapters instead of spacers. If you use just a spacer you'll need longer wheel lugs to make up the difference. Adapters bolt to the hub and have their own lugs. Thx that is a great site very very helpful......

That is what i found....these are what i am looking at currently... http://www.ilovebodykits.com/product/56343/TCS_Wheel_Spacer_25mm_BS_4X114_3_12X1_5_67_1mm_Bore.html They also make a 38mm but it is only in a 4x100 pattern and not the 4x114.3. Also what bore size does the Z use im seeing two different sizes a 64.1 and 67.1 bore. Quote Link to comment Share on other sites More sharing options...
deja Posted February 5, 2010 Share Posted February 5, 2010 Don't those wheels you looking at have both bolt patterns? But try these guys http://www.ezaccessory.com/Wheel_Adapter_4_Lug_4_5_To_4_Lug_4_5_p/4450-4450.htm They have a 1.25" which will get you close (35mm is 1.37") and you can specify your car so the lugs are right. And you can call them to make sure of everything. Sorry I don't know the center bore of our cars. I measured the bore on an adapter I have at 2 7/8" which is 73mm. Our cars are lug concentric, not center bore concentric so as long as the adapter/wheel will clear the hub you're good to go.

Yes they do have both patterns good stuff wasnt even paying attention to that in all my adapter searching lol, so with that being known would it be better to get the 1.25" adapter and be a little short or the 38mm adapter and be a little long? Thx for all the help and the good info too. Quote Link to comment Share on other sites More sharing options...
deja Posted February 5, 2010 Share Posted February 5, 2010 Thats a tough call. In a perfect world you want 0 offset. But given the tires size, fender and strut clearance it hard to know. You'll have harder time in the back than the front. I would error on the minus side rather than going too positive. Being off .2" isn't too much. I'm off a little over .1". Be sure to ask about the center bore. But you can always hog that out witha dremmel too, not a huge issue.

Kurai Posted February 5, 2010 Author Share Posted February 5, 2010 Thanks for all the help man it shouldnt be that big of a issue with the ZG flares as it is im thinking. Quote Link to comment Share on other sites More sharing options...
deja Posted February 5, 2010 Share Posted February 5, 2010 Yeah the flares will make it much easier. Thanks for all the help man it shouldnt be that big of a issue with the ZG flares as it is im thinking. Quote Link to comment Share on other sites More sharing options...
Kurai Posted February 5, 2010 Author Share Posted February 5, 2010 Hope so lol...now to just figure out the tire size to get that perfect fit with the ZG Quote Link to comment Share on other sites More sharing options...
sticky280zx Posted May 3, 2010 Share Posted May 3, 2010 heres the issue guys, you are looking at +35 offsets when you shouuuulllddd be looking for -35 offsets Quote Link to comment Share on other sites More sharing options...
Kurai Posted May 3, 2010 Author Share Posted May 3, 2010 Wouldnt -35 put the wheel way outside of the wheel well? The S30 has 0 offset right....help me if im wrong here i still get confused with this offset stuff lol, but isnt +35 mean the wheel/hub mating surface is 35mm AWAY from the center of the rim and farther away from the hub? hehehe and also been eyeing another set of rims lol tho I already have the 35mm adapters lol. http://www.mirowheels.com/STP1.html I just cant figure out what would be a good size tire to run on a 16x9 w/ZG flares on some kinda coilover setup.

sticky280zx Posted May 3, 2010 Share Posted May 3, 2010 275/40/17 for the tire, if you have a an 8-8.5 width wheel a -35 or even -40 will fit under a flared car with a very nice fit. The only thing you have to worry about is the backspace as in too + ...as in it hits/rubs the shock tower. But under a stock body z i would say an 8inch wheel +4 to -15 will fit, now 8.5 would need to be 0 to -5 on the small/strut side and maybe -10 or so on the bigger lip/fender side. Hope that helps -Jeff Quote Link to comment Share on other sites More sharing options...
Kurai Posted May 3, 2010 Author Share Posted May 3, 2010 What would be a good match for a 16x9? The Miro in a 4 lug only goes up to a 16x9. Im lost with this whole offset thing lol so ok the Miro has a ET of 15....so what does that mean? I was thinking that means that it is 15mm to the left of the center of the wheel if viewed from behind. Quote Link to comment Share on other sites More sharing options...
sticky280zx Posted May 4, 2010 Share Posted May 4, 2010 -15 pushes it towards the fender (left of center on the wheel from behind) +15 would be toward the strut tower, right of the center of the wheel from behind. And on 16inch its about the same 265-285 with a 40-50 profile a quick tire rack search would help find tires. Also i dont know if youve looked but we have some group buy wheels that would fit very well in the Group Buy section. Quote Link to comment Share on other sites More sharing options...
