5 Lug Conversion Kit Group Buy! $1900 shipped, limited time!!

[rongineer13]

The TRUE E30 5 Lug Conversion Kit is here.

And ready for group buy! This is no "bolt on" 4 lug to 5 lug wheel adaptor, this is a true conversion. German made E36 M3 hubs in the front and factory BMW E30 M3 rear hubs provide the additional lug, and E46 M3 brakes in the front paired E46 325i brakes in the rear provide a massive upgrade in stopping power! This means the E46 M3 factory 2 piece Motorsport rotor can be run in the front, and fully functionality of the stock E30 parking is retained.

There are 20 kits available at the group buy special price of $1900 SHIPPED. Group buy starts on 3/8/2013 and ends on 3/29/2013. After this, the price goes up to MSRP of $2499.

The first ten kits ship after the first 10 have been purchased.

For more information or to satisfy any curiosity, please visit my thread that has been up here on R3V since October of 2012: http://www.r3vlimited.com/board/showthread.php?t=265863

Every machined part in the 5 Lug Conversion Kit is 100% made in the U.S.A. with nothing but the highest quality materials, all machined by a highly skilled Swiss native and trained machinist here in Northern California. The pictures do not do the quality of work justice!

The front hub conversion assemblies are machined from 4043 Chromoly Steel, and the caliper brackets are machined from 2024 Aluminum and anodized blue.

This kit uses E36 M3 or E46 M3 front calipers, and E39 525i, 528i, or 530i all aluminum rear calipers.

Wow props for doing the hard work.
Have you mounted and tested this setup?

[StereoInstaller1]

Wow, what a great idea...beautiful.

Same proportioning valve and MC?

[JinormusJ]

This is way more practical than chopping up e30 m3 struts for my Ground Control conversion. With this, I can just toss on regular e30 struts with the 5 lug hubs and GC convert those

I am really excited for this product, and being able to run bigger brakes is sweet! I can't wait till I have some money to buy it.


Do you have any idea on fitment issues using 16" wheels?
Straight bolt on the rear regarding the emergency brake assembly

Wow these look awesome.

Now I need to figure out what E46 M3 calipers go for used and how what wheels options will clear them and still fit on an E30.

Thanks! I have had them mounted on my daily driver '89 325iS since mid October, and have put over 10,000 miles on them to date.

Wow, what a great idea...beautiful.

Same proportioning valve and MC?

Thank you! I am running the stock MC and stock proportioning with no issues, but the pedal does travel a little further than stock. The proportioning is not identical to stock, but I do not have a calculated difference.

The less of, or lack of, hacking things up was one of my biggest modivators in the kit design. I am working on a new front caliper bracket that will allow the use of E46 325i front rotors and calipers, which I know for just fine inside 16" wheels. And yes, straight bolt on in regards to the rear brakes and parking brake.

E46 M3, E36 M3, and (if I recall correctly) E32 740i calipers all fit the same. I am running E36 offset 17" wheels with plenty clearance, but those are easy!

These are really sweet man
How much offset do they add versus the stock e30 hubs?

[pilotskillse30]

great product! fill and redrill to late in my case.

Thank you, the front adds 12mm in track width, and I'm not entirely sure about the rears. Guess I should measure that! I'll get back to you on that.

Thanks! Well if you ever feel the need for ability to put all the loose objects inside your car through the windshield, you know where to find it :D

Great work Ron.

What about guys that have e30m3 suspension all around? Anyway to mount these brakes on them?

[rongineer13]

Todd,

First off, thanks! And yes there certainly is. I'm in the midst of working on the fronts, but the rear brakes are identical for the E30 M3, except you won't need the hubs obviously! If your serious about running E46 M3 fronts, there are a few different routes that can be taken; pm me if you want to discuss it further. Thanks!

Absolutely! Any time. Thank you very much.

Thanks!

[Wild Ride]

Fist off thank you for making this!

For comparisons sake. What is the added track width of an e36 5 lug and also e30 5 lug? I know this is a huge advantage of this kit is keeping close to a stock width giving wider tire fitment options.
