Hi guys, sorry if I post this thread at a wrong place.

First of all, yes, I have used the search button to find XD9 (I remember there were a few threads on this few months ago) but nothing came up this time.

I am planning to buy WORK EMOTION XD9 for my FD.
I have read a number of threads in the forum and it seems that many people prefer the fitment:
17x9 +45mm offset all round

However the some of the closest I can find for XD9 are (correct me if I am wrong):
17 x 8.5 with the following offsets 25/32/42 or
17 x 9.5 with the following offsets 28/38/44

Q1) I am thinking about getting 17x9.5 +44mm but just want opinion if that is the most ideal size I should get (I do prefer to get 9.5 because of the deep dish effect.)
Q2) I also want to hear opinion from you guys about which colour I should choose, out of (silver, bronze, white and chrome) my FD is black. (I personally do not want to have white rims because the contrast is too big, chrome XD9 does cost me alot more, bronze rims + black car is a bit common silver not sure)


Thank you guys
Eric

I know what is "best" really depend on how am I going to use my car for. Well i will inform you guys so you know what i want

I use my FD as daily driver, just street use, I still do not have the desire to take it to the track or drag race. 17s run cheaper tyres and little bit more fuel friendly as they are easier to rotate than 18s. I also want the wheels to be wide enough so they are almost in line with the front and rear fenders and will not sacrifice performance.

In short I want a balance between look and performance. Thanks!

efun007

Yeah I also love the look of having low offsets (GTR offsets) so the spokes will curl towards the center of the wheel.

But I really have limited knowledge. So please give me advice on that too.

Thanks in advance

The +44 will be just fine. You should go ahead and have your fenders rolled so you can use a good sized tire.

Silver or chrome would look nice. Chrome will require more upkeep, so that might be something to consider since you are using the car as a daily driver.

efun007

From the zip file, it says that the recommended front offset is 50, rear is 38. Should I go as close to those offsets as possible (which will be 44 front and 38 rear for XD9) OR 44 all round?

As for tyres, I heard that for 17x9 255/40R17 all round would be pretty good.
In my case where I am getting 17x9.5 would 255/40R17 be ok or something like 265/35R17 be most suitable?

Thanks guys : )

You could go with the 44 front, 38 rear on the 9.5, but the 44 all around would allow you to rotate if you also use the same size tire F/R, most likely a 255/40 If you don't care about rotation, you could go with a 255 F/265 or 275 R combo, or even go down to the 8.5 up front if it's just a street car.

FYI, nobody makes 35 series tires tires in those widths for 17". it'll be all 40 series.

rynberg

Yes, if you want to rotate tires, go with the 17x9.5 +44 with 255/40 all around. Fender rolling will be required up front.

Option B: non-rotatable, 17x9.5 +44 all around, 255/40 front, 275/40 rear
Option C: non-rotatable, 17x8.5 +42 with 245/40 front, 17x9.5 +44 with 275/40 rear

efun007

Thank you rynbery and ptrhahn.

I am quite addicted to the deep dish of the 9.5" XD9, so I think I will go with 17x9.5 +44 all around with 255/40 all round. This size will probably meet most if not all of my needs

Performance -> 17"
Show -> 9.5"
Cost -> 255/40 all around and able to rotate

I am a bit concern with fender rolling now. Any negative consequence? I will do a bit of research on this and see how would the fenders look...


Probably I do not understand the relationship between tyre width and offsets... Ptrhhn mentioned that: "You could go with the 44 front, 38 rear on the 9.5, but the 44 all around would allow you to rotate "
So does it mean having different offsets would not allow me to rotate because the width of the wheels are different now, aren't the wheels still 9.5" all round?

Thanks for the info guys.

Read the wheel tech section at www.tirerack.com. A 9.5 +38 will stick out 6mm more to the fenders than a 9.5 +44. That may not sound like much but it is a huge difference.

Rolling the fenders is invisible, as long as it is done properly and doesn't crack the paint.

efun007

Yes a 38mm will stick out 6mm more to the fenders than a 44mm, however, the width of the wheels are still 9.5" so why would that affect the size of the tyres? Why having a lower offsets allow me to use wider tyres?

The offset section of tirerack did not explain this.

Thank you

The further in the wheel is, the more tire you can fit without having issues of the tires being torn up from the fenders. The offset has to do with where the mounting location of the wheel is in respect to center of the wheel (just a basic explanation). The higher the number of the offset, the further it pushes the wheel width into the car.

This is also why wheels with lower number offsets, typically have more lip on them as the mount location of the wheel hub is moved inwards to push a majority of the wheel width out from the car.

Dorifto_PG

No. Lower offsets will just place the wheels further out towards the body of the car like it has been said in this thread. The reason for running lower offsets in the rear is that usually stock cars have more gap between the body and rear wheels than the fronts. So running lower offsets will move the edge of the wheel to line up better with the edge of the car. So even though the width is the same, the offsets can very well be different.





My suggestion: if you WANT to rotate tires, use the 9.5 all around with the +44 offset. Then in the rear, use a 6mm wheel spacer. It will give you an effective offset of +38 but it will not be a permanent part of the wheel, so it can always stay on the rear studs. Then when you rotate your wheels, the +44 comes off the front and goes to the rear (making is a +38) and the +44 wheel (looks like a +38 with the spacer) in the rear will go to the front, but like I said, since it is actually cast as a +44 offset, you can still use it up front.


This is of course assuming you want to run the same size tires all around.

efun007

so... offsets do not really affect the size of the tyres. Offsets only affect how "deep" the wheels can fit in.

Thank you.

Any chance I could use such size especially in the front without fender rolling?
With stock shock?
With aftermarket coilover?

Offsets can and do effect the size of the tires in the sense of how much tire can you fit without tearing up your fenders. i.e. with a higher offset number, you can use a larger tire size. With a lower offset number, you generally have to use a smaller tire or do what is the new crazy of "stretching" tires (i.e. using a tire too small for the wheel).

For instance, if you got a 17x9 wheel, with a +43-47 offset, you could fit a 255 size tire up front. However, with a lower offset, say +38-40 you would be using around a 225 or a 235 tire since you are closer to the fenders. Same wheel, different offset, different tire sizes. Just has to do with what type of driving you will be doing, fender pulling/rolling, suspension, etc. All of those things play a part in wheel fitments.

efun007

Thanks Mahjik and guys who contributed.

I see that having same diameter and same width but different offsets DO affect the tyre size. Hmm. I think what I dun understand is how having a more deep fitment (lower offest) actually allow me to use wider tyres on the same width. I guess it is bit hard to explain without diagrams. I will try to do my own research on that thank you. Point me to a few relevant links if you know any!


Therefore, for fd rx7, in my particular case
I should go with 17x9.5 +44 all round with 255/40 all round correct?

Thanks!!! For helping this newbie~

That would work just fine.

Here's an old picture of my FD with 17x9 +43 using 255's all around. That should be close to what you'll see:

1)mahjik
that looks awesome. probably no need the spacer for the rear wheel? or is it a matter of having better look? have u done anything to ur fenders or lowered the car? i am likely to run into the problem of rubbing the fenders and need to have them rolled?

guys i have attached few pics - 4 different colours of xd9 and another awesome looking fd i have found on the net.

2)that white fd is actually running on Gram Light 57 Pro wheels (18 x 10-in. +18mm F, +8mm R offset). can u guys tell if he has rolled his fenders? i dun think there is any wide fender.. how come he has no problem?

3)asking on behalf of another friend. he has advan rg 18x9.5 +22 all around and he wants to know if he can install that to his fd. - probably less extreme than the white fd size.

(should i start a new thread to discuss the gram light wheels so other ppl can involve?)

My car is lowered:

http://mahjik.homestead.com/files/FD...tein_stech.jpg

I do have my fenders rolled. IMO, any FD which is going to be lowered and use aftermarket wheels should bite the bullet and roll the fenders.

A few things that car has:

1. It looks like a fender pull
2. The car is using a small tire for the rims, therefore stretching the tire. This allows the sidewall to help clear the fender (i.e. running a 225 size tire on a 10" rim). Not ideal, but a lot of the drifting crowds do this.
3. It's also most likely running on some extremely stiff coilovers

You can make a fitment like that work, but its less than ideal and I don't recommend it.

Basically similar to above.

efun007

cool thanks. i can see that you mentioned 2 things: fender rolling and fender pulling- difference how are they different?

"bite the bullet"- Does fender rolling cost a lot?

Mahjik

iTrader: (1)

Yes, fender pulling does exactly what it sounds like. The fender gets pulled up a little to add some additional room. You may find pictures of JT-Imports' car where he had a pretty big fender pull on the rear.

Fender rolling is just rolling up the interior part of the fender. There is no exterior fender change so you don't notice anything different from the outside of the car.

No, it doesn't cost a lot, but you run the risk of your paint cracking. If you have a bodyshop do the work, they will usually make sure that doesn't happen but it's always a risk.

efun007

cool! i will do fender rolling once i have the wheels installed. thanks for helping guys! especially mahjik for repsonding all the time. really appreciate that.
