We recently received an e-mail from a customer experiencing problems after installing a KAAZ LSD (DBW3010) on his BMW E30.
He says after installation he has “found some vibration when taking a slow turn on the right and left” and asked us what might be the cause of these vibrations.
We explained to the customer that sometimes because the LSD tightens everything up, it just highlights other problems which already existed on car, but were not affected by a relaxed open diff. So the problem could be a worn bush, a bent arm or something.
We also highlighted a similar problem we have experienced where an Impreza pulled to one side after an LSD was fitted. It turned out that the car was twisted at the rear where the diff mounted onto the body of the car! Yet it didn’t show up so bad when the OE open diff was fitted.
Had a similar experience? Share it with us.

Car manufacturers are constantly improving and refining their cars and the parts that make them up. There can be some benefits for owners to fit the later parts to their earlier cars. Or sometimes this happens, when the earlier part fails and the easily available replacement is a later part, which may even be a used one from a car that is broken up for parts.
The AYC rear diffs on Mitsubishi Lancer Evolutions 4~9 are a classic example of this. These parts do fail and often people make the later parts fit their earlier cars. Which is fine, until you decide to modify or repair the newly fitted assembly – as you may not be ordering the correct parts to match the components now fitted to your car.

Your new Wavetrac® differential is incredibly durable and will withstand the harshest environment… as long as suitable oil is used.
Many customers ask what oil we recommend for use with the Wavetrac® differential. We feel the best answer is: Use the “factory fill.”

A potential customer called re clutch problems he has suffered with his Evo. 6 Tommi Makinen Edition – he has had 2 or 3 clutches in his E6 TM car this year (reckons he drove his E4 harder and never had any problems). Clutch the car came with didn’t last long, then he had a twin plate clutch fitted, which didn’t last 500 miles (he wasn’t sure what make). Then he fitted an organic or standard clutch himself – not sure if E4~6 230mm or E7~9 240mm and he couldn’t remember what flywheel he fitted, but despite that being OK initially it has now started slipping after just 4 months!
