Heavy duty side plate for IRS transmission case

Due to the increasing demand BBT has taken these aluminium heavy duty transmission case plates into the program. They are mostly adequate for use with gear boxes for competition. Most of the times these gear boxes had to be adjusted with a heavy duty differential (BBT 1420/1421) and strengthened driving shafts, resulting that the casing was suffering considerably. This heavy duty aluminium plate replaces the original cover plate and prevents that twisting forces can be developed which can lead to damage of the gearbox.
