i recently got a set of fd wheels for my fc. i was wondering if they would fit without having to put any spacers? if they would how many mm spacers would i need?

 

You will need at least 6mm for a very tight clearance.

 

How many mm should I have the spacers for them to be good? I've seen 20 mm in the front and 25 in the back. But what would be considered good?

 

I believe they are +50 offset stock. So if you put 20mm in the front and 25mm in the back that would be pretty cool. However, anything after 8mm spacers you will need extended lug nuts or hubcentric extended lug adapter/spacers. The later is the way to go.

 

If I used the Spacers would I need to roll the fenders?

 

Depending on your right height but most likely if it is lowered.

 

I've had a shop try 5mm and for the rear they said it was good but for the front they said 10mm should be fine because the wheels started rubbing against the strut. Is 20 and 25 for the rear really the right length?

 

Hello, i have the same rims for my FC as well, contact "ARD T2", he's on the forum. He has the whole conversion setup. Just shoot him a PM for pricing.

 

Alright. Thanks.

 

There really isn't anything conversion about it. Just get some spacers and slap them on. If you want anything past an 8mm spacer (and only that leaves you with only a couple threads) you will need extended lug nuts. Depending on your strut/spring combo an 8 is the minumum you can use to run FD rims up front.

20 and 25 is more than enough to fit FD rims, but would be good because of the wide stance you would get. Although depedning on how low your car is you might have to roll the fenders with that setup.

Something like this is good, just find it in the mm you want.

I know this because I have multiple friends who run FD rims.

 

And what if I have coilovers on them?

 

With the adjustable ride height you can just adjust it high enough so you don't have to roll the fenders if you get really wide spacers.

 

Alright.
