According to many the stock BMW Mtech I steering wheel is the cheapest, best steering wheel for any e30. It’s period correct, sized so that it does not block the driver’s view of the dials and has 3 horn buttons which can be pressed without ever taking your hand off the wheel. It’s perfect for everything including city driving and spirited back road hoonage.

For all those reasons I put off, and put off, buying a new steering wheel. But on May 4th I’ll be participating in the BMW CCA GGC’s HPDE and I felt it was time to update my wheel. The biggest motivator is that there is not enough room for my leg between the wheel and gas pedal when heal-toe braking / blipping the throttle. I’m only 6’1″ but I have to twist my leg in a weird way that just barely works and is generally clumsy. As well my old wheel has no leather texture left and is unpleasant for long drives without gloves.


Admittedly I bought a new steering wheel based on looks and community opinion of the manufacturer. I’m becoming a rally racing fan and the yellow center marking on the Momo Mod 7 has big appeal. Because I was already placing large orders for M20 parts I decided to just add a wheel to my already huge order, save a couple bucks on shipping and just go for it. I put the wheel on this morning and drove to work only once but I can already feel that the light weight and smaller diameter makes the wheel easy to turn and grips nicely.

The BMW horn button is after-market and hard to find. Initially I was searching enthusiast forums but found an inexpensive plastic version with the perfect fitment on Aamzon for less than $20. Links for all items are below the photos.

I found an even better steering wheel -BMW M-Tech model to replace the 3-spoke Sport wheel I have now. It needed quite a bit of work as the leather was cracked and someone had leaned a car door against it which scuffed the leather and crushed the foam padding. On a scale of 10 it’s probably a 4/10.

I used Leatherique Leather Restoration products for this. This is my third time using this system (second steering wheel) and I’m getting better each time.

Step 1:

  • remove dirt from the leather with a damp cloth, clean the vinyl with Vinylex (or similar vinyl care product)
  • applied “Leather Rejeuvenator” but any non-waxy leather care product would probably work
  • cleaned the leather with “Pristine Clean” (not sure what it is, some kind of mild solvent)
  • allow the leather to rest for 48 hours

Step 2:

  • using 400 grit sand paper wet with “Super Prepping Agent” (another solvent, definitely contains some acetone) removed most of the old dye, smoothed off any raised parts of the leather
  • filled the crack with super glue to keep the edges from curling up
  • used leather crack filler (almost like plaster but with quite a bit of flex in it) and 600 grit sand paper to fill in cracks and crevices
  • allowed crack filler to dry for 20 minutes or overnight
  • kept using crack filler and sanding until smooth

Step 3:

  • applied dye using a foam brush, allowing 20 minutes between coats
  • let dry for 48 hours

Theoretically I should be able to use 1500 grit sand paper to wet-sand down any spots where the leather die has gone on unevenly or a droplet has formed but everytime I’ve done this on a steering wheel it just sands right through the new dye. Instead, gently dry sanding for only the shallowest of problem areas seems allowed. It’s more important to put on thin coats and take your time in the first place rather than fix it later.

I’d rate the wheel a 8 or 9/10 now. The leather used on these wheels doesn’t usually have much texture to begin with and after decades of wear and tear and my restoration there is even less leather grain left. Completed job:

Seller has a $50 steering wheel they are trying to sell for $140. This is the same model of steering wheel I got from Pick n’ Pull for $15 which I restored and re-dyed. For reference, this page has the canonical e30 steering wheel guide with prices which is where I got that $50 price from.

Oh look, here’s another one. I guess ridiculous prices on these are pretty common… maybe I can get $140 for mine once I’m done with it.
