As I'm sure my name infers, I'm a nissan enthusiast born and bred, but I've always had a soft spot for both FC and FD model RX7s and the opportunity has come up for me to get a 93 FD twin turbo. I'm used to wheel fitment on all the 240sx models I have owned and I know RX7s are very different. I am not opposed to rolling fenders and even doing slight pulling, but don't want to mess with the stock lines of the fenders as I think they are gorgeous as is. I'm somewhat of a fitment *****, so I'm very picky about how my wheels fit. At first I will only be running a set of coil springs and struts, but will be upgrading to coilovers very soon. My question is how will the fitment of this setup be as far as stock body panels is concerned. Again, I will go as low as possible for flush fitting wheels and am not opposed to rolling and pulling, as well as negative camber.

NINJA EDIT: I searched and found the fitment thread with the excel spreadsheet, but I'm a computer idiot and don't know a thing about excel or how to get it, I'm a car guy, not a computer guy. Sorry if I'm causing unnecessary issues, but I want to be very serious about this car if I get it and who better to ask than those of you who have learned already. I'm no child asking rediculous questions, just someone who wants to know and learn and I appreciate any help in advance.

You didn't post tire sizes. So I'll assume you run proper sizes for those wheels which would be 245/35/18 up front and a 255/30/19 out back. Given the low offsets of those wheels, you will definitely not fit the fronts without an extreme roll and pull up front and probably a 225 tire, even then I can't say that you won't occasionally hit the fender if you drop your car too low. I would say that the wheel up front will probably be sticking about .25" past the front fender. The rear should be fine however, maybe a slight roll because of it being a 19" and rubbing during hard corners, but it should also be said that a staggered 18/19" wheel combo will look strange on an FD.

IMO I would get new wheels. The offsets are too low to run proper fitting tires and the wheels could be wider if the offsets were higher. On the FD it is even possible to run 18x10 +50 285/30/18 all around, to give you an idea. Its your car, so do what you want, but be ready to do some work to get that front to fit.

thank you. I haven't purchased the equips yet, so I probably won't now that I know. So being as you can run an 18x10 all around in +50, you could do say 18x9 +24 in the front just to get a little stagger (1 inch=25.4 mm)...

can't tell from the picture whether or not the suspension was under load in that picture and I don't really have enough experience with FD suspension to know whether or not it reacts differently when compressed or not. The volks I currently run on my S13 look about that way when unsprung, but sit perfectly flush when under load. This picture is before the fenders were rolled, but now that the fenders are rolled I get ZERO rubbing issues... well except for the main harness in the passenger side front and that is a tad of a sore subject with the design of the 240 suspension as the coilovers compress the wheel/tire move upward and inward, on an FD I don't know, maybe you could enlighten me.

Basically, you have choice to make. Can you make offsets like that work? Sure! However, you will sacrifice some handling (i.e. camber adjustments) and tire sizes. If you want to run stretched tires as a lot of the 240 guys do, you can make it work. However, that's not really the culture here so a lot of people will generally frown on that on this forum.

The culture here would rather have as much tire as they can get under the car. Therefore, the offsets they use and recommend are much more positive then what you are looking at (hence the +50 recommended a few posts up).

gotcha, I just want to see what will fit for say a set of nice wheels for the street, probably stretched tires cause I have grown accustom to that look. Once the car is ready and safe for track usage I will run a much different wheel tire combo as I am very keen on the difference between look and function. I am EXTREMELY against racing in any form on the road so having utmost performance function on street isn't as important. I appreciate your responses very much by the way.

18x9 +37 with 245's and 18x10 +37 with 265's

I'm really liking what I'm finding as far as fitment with these sizes, a thread fairly new in this section with SSR SP1s...

If you're coming from the 240 scene where a small stretch is common, those fitments sound like something you'd be used to. You'll still be rolling the fender to prevent damage with those wheel sizes, but they'll be a lot better than the original equips. For reference, I run an 18x9 +43 with a 255/35 up front, and a 18x10 +43 285/30 out back on stock fenders. Thats about as far as I could push those tire sizes on stock fenders, so as you take off offset from that fitment, you'll have to take off tire and increase camber slightly. Perfectly in line with the fitment you posted above with 245 and 265 size tires. FD offsets aren't terribly complicated, but you just have to know that you quickly lose available tire width when you lower the offsets.

appreciate your response... yeah, If I end up getting this FD, which I'm really hoping, my above combo will be the sizes I go with, maybe not SP1s, but an 18x9 +37-40ish and 18x10 +37-42ish with 245s and 265s, both 35 series tires, which will moderately stretch both front and a little more rear, shouldn't have to run more than -3 camber either front or rear... don't think anyways.

Very ironic that you say that, not everyone on this forum would agree with you there haha
