new wheels tires and spacers help please please please

[uwrasta]

currently:

Lowered HR sports springs 1.2" front 1.6 " rear

245x40 R17

with enkei klamp 17x 7 with I think a 48 offset

putting on

225x45 R17

with enkei RP03 17x8 with 48 offset so i'm told

I could find the offset marked anywhere or maybe I'm looking in the wrongs spot. I have wheels off but maybe i'm half blind in my old age.

? when I took the old wheels and tires off and put new on the wider rims and tires rubbed the springs. I have some eibech 20mm spacers but now it seems like they stick out to far and the nuts have little thread to bite.

does anyone know the correct spacers I should be using with the size tires I have right now they are 20mm and I have a set of 25s

look at the pics and see what you think I have no spacers in the rear but that just don't seem right



thanks all

Should move this to the wheels and tire board...

So essentially you went 1 inch wider wheel on same offset... which means you decreased your inside clearance by 12.5 mm.

There is no "correct" spacer size, it is subject to taste as long as you are adequately clearing your suspension...

My personal taste would be for a 10mm spacer...

Whatever you do: DO NOT RUN STOCK STUDS with these spacers (either your 20mm or 10mm). Get extended studs for proper engagement.

Enkei puts the offeset in the back side hub area of the wheel. It will be next to size, i.e. 17x9 +35 or 17.9 ET35 or 17x9 35. Those are just examples.

The previous wheels have stock specs thus the 20mm spacer worked, alot of people use 20/25mm spacers on stock wheels. So your new wheel adds 1" overall thus adding 1/2" (12mm) to both sides as compared to the previous wheels. So the fender side of the new wheels stick out about 12mm more then the previous wheels. If you want it to look the same you will need to minus the 12mm you gained from the 20mm spacer. So that will put you at a 8mm spacer. So you will need a 8mm spacer.

This is to small for a bolt-on so you will need this in a slip-on. With that 8mm is to much spacer for the stock lugs, so the lugs will be need to be swapped out for longer ones.

Thanks a lot guys!!!! I really appreciate. I will check the offset for sure and make sure they are identical in offset and diameter. Either way it sounds like 20 front and 25 rears will work. It's just a question of whether that will work with how far it's been lowered. I'll **** around with it some more this weekend.

So ? If I use longer studs with the 20-25mm spacers. Will they be to long for the stock wheels if I want to swap out??? I'm sure I could do some math and figure it out but I don't wanna hurt my brain

?? What length lug bolts are people using???

The 20mm spacers you have are slip on or bolt on, a google image search will clarify if you don't know?

how much drop do you want? Are you going with spring or coilovers?

You can use the 20mm with new wheels but you may have to run more then usual camber to get the tread under the fender. Whether or not you have a bolt or slip on type spacer will let you know what you need to do with the bolt. I have feeling they are bolt on spacers because it is not recommenced to us that large a spacer for slip ons.

edit: check this thread. BRZ with no spacers and dropped and a FRS on stock suspension with 23mm and 28mm spacers.

thanks i'll check it out.

[uwrasta]

they are bolt on. thanks

@uwrasta it looks fine to me. That is how they are supposed to sit. If anything you could run a 3mm slip on spacer. Or look up youtube to find out how to measure the offset. Or look on the back of the wheel. 8"width and +48 offset is roughly equal to 9" +35 on the inside clearance. Many people run that size with no problems.

are you saying they run the 8" x 48 with a 3mm slip on??? what are they running on the back??

thanks

No. I am saying they clear(with the same amount of inside clearance as 17x9 +35) and so should yours, if they are +48. But if you need a small amount of clearance like some of them do, 3mm should be enough. And it is usually in the front.

17x8 +48 with a 20mm or 25mm spacer should fit. Not sure about your "not enough thread to bite" problem.

Take better pictures. The pic of the front looks fine to me. The rear pic is at an angle and it looks like your wheel has 10 degrees of negative camber.

Take pics with the car on the ground and not in the air.

You are working with 20mm's here. If they don't fit without them, and they are too far out with them... split the difference. It is just THAT simple. Or realize that you are probably being really picky and that the lower portion of the fender isn't 100% vertical.

In the end, you need to find out the offsets for anyone to help you. My advice is based on the assumption that it is 17x8 +48.

In the front with 17x8 48 offset + negative camber, it will rub. because I had the same set up.

Without negative camber, running 225/45. you should clear the oem struts. But to be safe from rubbing, You can run a 3mm on OEM studs, Make sure the lug are torque down properly.

However since you are lower, the car will gain natural negative camber, so you might run into rubbing issue with the OEM Strut Perch (base)

I would recommend getting ARP Extended Stud, along with Open ended Lug nut. then throw on a 5mm spacer, you should be able to clear the front.

I would stay away from 20mm-30mm adaptive spacers. In MY OPINION I do not trust spacer on my car.

I hope this help, I had the same fitment issue when my previous set up.

Edit: Minor stagger in offset (5mm) in the front compare to the back shouldn't effect largely on your car handling. ARP stud are extremely easy to install in the front, but its more difficult in the rear. So leave the rear stock and do not run any spacer, or you could throw a 3mm spacer in the rear.

[KnightRyderx2]

Leave the 20mm/25mm spacers on the front and back, put the wheels on, and put it on the ground. See how you like it like that. In the air the wheels will look straighter then when on the ground so you will not see the camber like that. Just dropping the car will apply a little natural camber. Keep in mind that the top of the tire will go into the fender a little bit when you drop it.

If you dont like the way it looks, to much poke at the point, adjust the spacers. Go down to 15mm or a 10mm, but at this point I suggest getting slip on types with longer bolts. If going this route get a package deal that comes with the spacer and bolts then you wont have to think about it; Ichiba, Eibach, just to name a couple brands.

I think it looks pretty good with the spacers, front and rear. Then with about a 1.5" drop, maybe a little more, it will look even better. Get an alignment with about 2 to 2.5 degrees all around and it will look awesome.

[uwrasta]

Thanks. I have an alignment set for next Thursday. I would prefer a slip on spacer so I can more easily switch the tires from 17x8 to 17x7 and vice versa.
? If I was to space the 17x8's then witch back to the stock size. Will I need to align every time?? I wanna have a set for wet and dry track as they are easy to transport in the trunk.
Thanks guys. 1st things first I'll double check offset to make sure.

The 17x7s would have no problem with the 20mm/25mm spacers you have right now. I really dont see a need to get anything else, other then camber adjustment items; camber bolts and/or rear LCAs. I wouldn't waste my time or money with new spacers, but if you don't like the way it looks its ultimately up to you what you want.

You will not need an alignment when you swap only wheels.
