Now that you have them put together and installed, what's the final specifications for everything (wheel dimensions, spacer dimensions, etc)?
Please note that I'm still actively searching for rear lug bolts. The most difficult part of this fittment has been aquiring the correct lugs & lengths. I'll get to those in a sec. The wheel specs are as mentioned previously in this thread @ 15× 8.25 with a +20 offset. The tires are Nankang NS-20's in 185/45/15 with a V speed rating. These are a very uncommon (in the US) size, and had to be purchased from the UK (thanks Ulix). Mounting consisted of custom 4x98 to 4x100 in 20mm thickness, (for the rear) adapters. Specs are 58.1 to 58.1 hub bore/mounting hub with standard Fiat M12×1.25 thread pitch. Again, sourced from the UK. The fronts are standard Eibach 4×98 hub centric spacers, in 10mm thickness. The fronts required this type of spacer, as it provided a stock 58.1 mounting hub, so centric rings (for the wheels) could be fit. Unfortunately stacking OEM spacers, can not work for this, as they are void of the centric hub. The wheels themselves have a 68.1 center bore. This is where keeping the custom and off the shelf spacers, with their 58.1 centers, comes into play. Instead of having to purchase different sizes on centric rings, I was albe to use a single set of 58.1 to 68.1 rings. This is ideal for future roadside repairs and helped keep the costs down... Even if it was only a $14 savings
. As I mentioned earlier; the lugs were the real PITA. Since the front spacers are 4x98 only; wobble bolts were required. The jump from 4x98 to 4x100 is very minimal, so for simplicity and time, it only makes sense to use the wobble bolts. I could have probably used OEM bolts and slightly sanded the bolt holes on the wheels; why chance it, though? I ordered 16 of these. The wobble bolts are again in standard M12x1.25 by 60mm (35mm grip). The rear lugs are a mix of OEM lugs and "collars" from the other 8 wobble bolts. Since the rears are adapted to 4x100, there isn't a need for "wobble" bolts. I used the collars with or lugs, only because the ball seat of the OEM lug, is too narrow, for the wheels. I will buy some new lugs in a few days. In the meantime, it's like 70° out and I'm gonna drive the car today, so they will do, for now.
Everything was finally assembled yesterday morning, so it's very recent, events. While on the test drive yesterday, I could hear some scraping of rim to suspension, up front. Since I was running late for work, I parked the X and took my daily, instead. This morning I woke up extra early to fix the rubbing. I removed the wheels and could see a very slight rub on the helper spring, of my coils. A couple quick passes of an angle grinder, and it's as smooth as butter.
The only varience in specs that I would change, from those mentioned above (and with a far deeper budget) I would have the rear spacer/adapters speced to 23-24mm and the fronts to 11mm.
