You sound like a very sharp guy. I’m looking to put the largest set of wheels that will fit on my ’74 Datsun 260Z.

It has mostly stock f/r susp. except for stiffer springs & sway bars.

It also has fiberglass front fenders w/appx 1.5″ flares as well as fiberglass rear arches w/appx 3″ flares.

I now have 70′s style wheels/tires: Western brand 14X7 running fat Gr60/14 McReary radials (yep, they’re old!)

Can I fit a set of 17″ or 18″ wheels with my stock susp/brakes? I’m not looking for super-wide tires, I just want to fill out the wheel wells w/modern wheels/tires.

I’m willing to use spacers & longer studs, but I don’t want the expense of coil-overs!

Thanks for your help,
Bill

you’re going for negative camber.

Positive and 0 camber are not ideal for performance.

always aim for ZERO toe as well.

If you’re looking for more grip, you need to be sure you’re looking at Extreme Performance Tires. Not some $50 a piece tires.

The BC Racing coilovers will help with the fitment. You’ll want to roll the rear fenders, like we said.

the 235/35/18 may be too tall, initially stick to the 225/35/18 (if you can find any).

the +25mm offset will be harder on the bearings, causing increased wear. Your car will most likely tram line more often.

this isn’t going to be a bolt on setup, you’ll need to do adjustments/modifications to make it fit correctly.

when i go this wide the camber will go postive or negitive..?and if i will have to adjust it..should i put it 0 or a bit negitive..? since i do aggressive cornering..?

i googled..i found a front camber kit..for my lancer..the rear is adjustable..also i will be using BC coilovers they have front camber plates as well..

i could get those and roll the fenders..

do u think i may face any other problems..?

i even thought why dont i go 235/35/18 since the diameter will be simillar to 215/45/17.what do u think.?

too many questions

thanks.

currently running on my car 215/45/17 no rubbing..

so what do suggest how can i work this out..?

thank you

you will most likely also have to add some additional camber on top of the fender mods.

what size tire you looking at running?

my car is 2004 lancer ES..

there is a guy Running 18×7.5
Offset = 38 mm
Width = 7.5″ =190.5 mm
Centerline = 95.25 mm
Backspace = 146 mm = 5.74″
forwardspacing =2.753″ (no fenders mods needed)

everything is fine with this offset in his car which is 2004 lancer ES as well..

i came up with this wider size with different offset..and its my plan…

18×8.5
Offset = 25 mm
Width = 8.5″ = 215.9 mm
Centerline = 107.95 mm
Backspace = 154.65 = 5.73″
Forward spacing = 95.65 = 3.76″ (i can work somthing out for the fenders)

i am doing this because i really need traction..my car has an evo engine(swapped) and its FWD..

so what do you think abt it..is there anything else that i have to worry abt..?

thank you…

t3h_Clap asked what you vehicle’s wheel width is, NOT the tire width which was the ’235′…seeing as you have a P235/65R17′s, you probably have a 17×7 or 17×7.5…when He also asked about ‘stock’, that meant the OEM factory spec….

Also, adding a wheel spacer is just gonna make your tire stick out by a good 2 inch, rubbing against the fenders and the wheel well.

…not good for looks, not good on your suspension…knowing BMW’s have tight suspension, you might have to spend for a ‘lift kit’ if you REALLY want THOSE nice-18mm-offset RIMS…which defeats the whole purpose of a BMW…

Also you might want to measure your OEM backspacing to find out how much room you have for aftermarket rims, so they don’t RUB against your suspension parts…measure from the rim’s mounting pad up to just before the lip of the rim, not to the edge of the tire

So overall, you might for a rim that has a medium to high offset…limit it to 25mm if you have to, and don’t go over 40mm….

you OEM rim is probably a

…17(size)x7.5(width), P.C.D.(pitch circle diameter or bolt pattern)is 5(bolt)x120mm(or 5×4.72 inches), wheel stud size is a 12(mm)x1.5b(tread pitch), center hub bore is 72.56…

Everything is stock, wheel width is 235.
I dont want to change any tire sizes, just keep the stock 235/65 on 17″ rims

it depends on a lot of things.

1.) what car?
2.) what suspension are you on?
3.) what is the width of the wheel? what is the width of the stock wheels?
4.) what size tire is standard, and what size tire are you hoping to run?

there isn’t a Yes or No answer without more info.

if something wheel related needs further clarification don’t hesitate to ask.
