Anyone running LTW5 (D-Force) wheels?

Im deciding between those and the MT1 from Tirerack for track wheels (and daily use for the time being)

Sizes for LTW5 are:
18x9 : 41et (front)
18x9.5 : 35et (rear option 1)
18x10 : 43et (rear option 2)

Im a bit skeptical because most people seem to be running an 8.5" front wheel with a 245 tire and a 9.5" or 10" rear with a 275 tire. Im not sure if Id have trouble with a 9" front, and the 18x10" offset doesnt seem aggressive enough...

Leaning towards the MT1 for convenience sake but just trying to weigh the options.

I went with the MT1's myself since I like having the ability in a pinch to order up a wheel and/or tire and have it delivered in a day or two without any issue. They've been VERY strong as I street drive in both Boston and New York City. I've been impressed.

So, I'm lowered quite a bit. No tuck. No gap. It is lower than most. Note that coilovers free up quite a bit of strut-side room up front. I run about 1.8deg camber in the front (on the street) and 1.7deg camber in the rear. So here are my findings...
  • An 18x8.5 or 18x9 wheel will work fine in the front with the correct offset.
  • An 18x9.5 or 18x10 wheel will work fine in the rear with the correct offset.
  • For the front, a 245 tire works for offsets in the range of +38-45.
  • For the front, a 255 tire works for offsets in the range of +38-41. The higher the number, the greater the chance is you will need to run a spacer to clear the strut. The lower the number, the greater the chance is you will need to dial in more negative camber to clear the fenders.
  • For the front, a 265 tire MAY work for offsets in the range of +38-39. I may try this out when it comes time to get new tires but it'd be done with a wheel change to 18x9 which I don't believe the MT1s are available in.
  • For the rear, a 275 tire works for offsets in the range of 25-30. The lower the number, the closer you'll need to be to stock ride height and/or you'll need to dial in more negative camber. The higher the number, the greater the chance is you will need to run a spacer to clear the inboard lining.
  • For the rear, a 285 tire MAY work for offsets closer to to 25. Again, the lower the number, the closer you'll need to be to stock ride height and/or you'll need to dial in more negative camber.
This is based on the following personal experience...
  • I run 18x8.5's +44 up front with a 255 tire. The inboard side of the tires rubbed a bit with this more-than-usual upsizing so I installed a 3mm spacer and it fits perfectly. The spacer makes the offset effectively 41mm (same as the LTW5 you note above).
  • I run 18x9.5 +35 out back with a 275 tire. It rubbed quite a bit on the inboard side so I installed a 5mm spacer to give me an effective offset of 30mm. Now it rubs extremely rarely on the inboard side and since cutting out a bit of the plastic liner (very minimal amount has been cut) it doesn't rub at all. I ran a 10mm spacer just to experiment to give me a +25 offset and it rubbed on the fender when the suspension was very compressed (i.e. on track with full lateral loading). I believe my ride height factored in heavily here.
For the options you mention, the front should work perfectly with a 245 tire. Both rear options will require spacers of varying sizes regardless of chosen tire size.

Hope this helps!!

Wondering if anyone has actually installed LTW5 18x9 255s on front and back with any problems or work arounds on a non-m z4? i'm thinking about getting the wheels and a ground control kit too. either way, i might pull the trigger and hope for the best!

The 10" wheel would need a spacer to correct the offset. That 10" wheel was designed for non-m cars that need a high offset+rolling to fit a wheel that wide.

The 9 and 9.5" wheels will work. Do note that none of their 18" ltw-5 wheels meet JWL standards due to their low load rating. Some of the vendors disclose the wheels as "not recommended for street use" and some don't.


Do you know what tires you want to run for street/track? The actual tire will have a big effect on fitment as they vary significantly. Also do you have any modifications?

There are a few threads floating around about the APEX ARC-8 wheel. You can see varying wheel sizes and tire choices that people have mounted on their M's.

For a track setup I'd recommend the 18x9" et42 wheel and the 18x10" et25 wheel. If you add some negative camber to the front in the future, then you can mount up some 255/35/18 r-compounds in the future as the wheels become a more dedicated track set.

Bumping this up from the grave!

I'm in the market for some new shoes for Bianca. I will be using the shoes as daily drivers and autocross wheels. I plan on as much sidewall as I can squeeze into the wheel wells. I'm coming from a set of ZCP's that were heavy as hell.

I like blocky spokes and have been leaning towards a set of Enkei Kojins, like what I had on my 135i. The cost/weight seems right on the Kojins, and I have used them before for the same purpose. Looking at the weight savings from the ZCP's, I'm shaving 12.5lbs total for the set.

18x8.5 20.9 lbs
18x9.5 20.6 lbs (?)

Looking at the D-Force LTW5's, I'm cool with the style, but the weight savings is much better for about the same price. The weight saved from the ZCP's is 29.4 lbs total!!!

18x9 17.8 lbs
18x9.5 18.4 lbs

So my question is.... Who has used these wheels now (6.5 years after first post)? If you have, what are your thoughts? I know some vendors don't like them, and even my local shop recommends against them, however he's sold a ton of them and never had a single complaint.

I ended up with the TRMotorsport MT1 from tirerack
18x8.5 (+44) and 18x9.5 (+35)
