    Dear Sirs.

    My name is Stelio, and I am from Montevideo Uruguay (South America).
    I am interested in acquiring a gear kit containing a gearbox , pinion, bevel ring gear and a limited slip differential for a Honda Civic VTI sir EK4 , B16A2 engine .
    This is a Group N Rally car , and it´s current is an S4C .
    What i need is a gear kit with the final drive ratio being 5.545 (61 /11) and 1- 2.428 34/14
    2- 1.813 29/16
    3- 1.421 27/19
    4- 1.174 27/23
    5- 1.000 24/24

    Final 5.545 61/11

    I would like to know if your LSD`s meet the standars approved by the FIA for a group N rally car (homologation N 5552) , since we are only allowed to use mechanical LSD`s based in friction discs, and not in the Torsen system .
    I would appreciate if you could give me the price of such product

    Im hopeing to hear from you soon
