ok here is the deal i got a great great deal on a set of FD rims now i did some research and i found out that i need 25mm(1 inch) spacers. do i need them on the front or the back? or both? that is one and the other reason why i am scared is because my stock size is 205/55/16 these tires are 225/50/16 will i have a problem with these tires rubbing on my fc? the fc is lowered 1 inch with the racing beat springs and tokico blues! thanks for the help

so you need spacers becuase the offset of the rims is wrong right? and how wide are the rims??

i run 225's in the front of my fc on stock suspension with no rubbing and 245's in the back that only rub if i take a uphill corner way to fast heh

If you have dialed in at least 1 degree negative camber on the front it will fit with the proper offset.

My suspension is similar to yours and with 16 x 8 +34 offset wheels you should be able to put 245s on.

I have noticed that my S5 has slightly more inner fender clearance than an S4 mostly due to a screw top dead centre which you may have to remove.

Try them they should work fine.

ok now that i am doing more and more research on it the more i am getting scared! the wheel spacers! i am going to need spacers with longer bolts? when i was thinking spacers i was thinking of those thin 1/4 inch spacers you buy at the tire shop! so why is it that i can't put the wheels right on? why is it that i need wheel spacers? and how come i can put them on in the back with no spacers but i need them for the front? i am so lost i think i just might sell them!

how about you just go out there and put the wheels on your car. when you lower the jack do it really slowly and watch for anything thats gonna hit. if nothing does turn the car on and turn the steering wheel and watch for rubbing. its not difficult, youre asking too many questions. just put them on the car and check it out for yourself.

the problem with those rims is that the hub is smaller on the fc than the fd. I was in your situation a long time ago. It sucked because i lost money selling the wheels. THe spacers push the rims out so that they don't rub and so that they fit on your hub right and don't put pressure on your wheel stubs. Good luck.

What offset are the different wheels? On each set of wheels there should be ET"some number" stamped somewhere. If they're the same then you don't need spacers, if they're not then if the new wheels have a higher number than the old ones then you need spacers with a thickness equal to the difference between the 2 numbers. If the new wheels have a smaller offset than the old ones they won't work.



Re. spacers, get the ones with the longer studs and steer well clear of the ones that come with integrated studs that don't go right through the hub. You will need spacers for all 4 wheels.

well i always thought the fourms are where you ask all your question! i rather hear everyone tell me what they have to say and why before i go out there and break something! just because you know it all and you have a ton of loot in your pocket doesn't mean i do! i want to know so i do it right! i rather wait and do it right then do it wrong it will cost me more in the end!

This is both right and wrong

This statement is correct only if the wheels are the same width.

If the wheels are of different widths you need to work out the back-spacing and keep that number very close to the same.

Having said that, there is extra room to go deeper on the back spacing than a stock wheel does.

Why don't you just turn around them and sell them if you are so concerned about everything?

The offset on FD wheels is + 50mm. The offset on a stock FC wheel is +40. The FD wheel is a 8" wheel and the FC wheel is 7" in width.



To run a 16x8" wheel in the front (since the macpherson suspension gets in the way) you ideally need +27 offset on a 16x8 wheel.

50mm - 27 mm = 23 mm spacer, or something close to it. 1" is 25.4mm. You will definitly need longer wheel studs.



If you have more concerns you should do some more searching. A good place to start is:

On my car, I have 10 mm spacers on the front and they dont rub and I have no problems with it. I also only have a 215 tire.

Not as far as I'm aware, you need to keep the offsets the same and not the overall track width.



Mark

you are wrong on both accounts, its just common sense that if you take your time and pay attention you wont break anything.



what are you going to break if you take one of your current wheels off and try to put the other one on? if the strut is in the way then you wont be able to get it on, which means you wont break anything unless you try to force it. if the strut isnt in the way and you gan actually get the wheel bolted up look and see if it will clear everything and if it looks like it will then let the jack down slowly. the key to all of this is to take your time and make sure it will work before you screw something up.

It has nothing to do with track width

1) you have to clear inboard items, in this case it is the spring and perch that is the issue. So changing wheel width and keeping the same offset gives you deeper backspace which equals interference in said spring perch.

2) The width of the assembly also has to clear outboard items, in this case the inner fender. Most of us want a wide rim, so you need to do the math and work outward starting with the BACKSPACE required and then ensure that it will swing inside of the fender well.

I'm coming at it from a handling point of view, you need to keep the offsets the same to keep the right suspension geometry - in the front at least.



Mark

I completely understand and agree with your reasoning.



IMO the amount of leverage change by adding adding 1" or less to your track is negligable and is also compensated for in the upgraded suspension components.

Not to mention the extra grip that you will get and it looks WAY better.

I ran this setup for about a year.



I had to use spacers in all 4 wheels to keep the tracking with it spec. IF you only run spacers in the front it will look like a drag honda.



At first I had the stock size 225/50 r16 they rubbed badly. I only had eibach spring with AGX shocks. You had to be careful taking a turn and turning to a drive way. It would damage the fenders bad.



I then ran 225/45 r16 and was able to get the rubbing to a minimun.



I love how the FD rims looked but it caused weird handling, and put stress on the front wheel bearings. I hardly recommended because of that.

where you running wheel spacers on there? i just got a set of wheel spacers but i have not put it on the car yet to cold and the holidays!

its says he did

yeah but i meant the ones that have the lugs on it because he said he used spacers and extra long bolts, i just don't want to get something where i am going to have my fc messed up in the end, but i got the wheel adapters on the way so we shall see what happens!
