Our new generation of VT-VZ IRS Kits are now available! These kits allow you to shorten the rear wheel track on your Commodore as well as eliminating 90% of the flex that the factory control arms and bushings suffer from under hard launches and cornering!
This Listing is for-
1 x Pair - SCF Shortened IRS Trailing Arms 1 x Pair - SCF Custom Length Driveshafts (OEM Power Rating. Higher HP rated Driveshafts available for additional cost)
These arm's have been designed to shorten the rear wheel track 100mm/4" per side! This Kit will ONLY work with split mini tubs (Factory Wheel Tub moved across to the rail, The area of the wheel tub needs to move across all the way to the chassis rail to clear the shock) and providing you have the correct width/offset wheels (See below)
Not only do we shorten the track but we also run a Chromoly tubular outer arm and Chromoly Teflon lined heim joint & threaded adjuster which eliminates all of the flex that the outer bushes suffer from under hard launches in drag racing and heavy cornering in drift/race applications, and to further aid in ease of alignment we have fitted SuperPro Adjustable bushes to the inner pickup points. These Kits also do away with the poorly designed/weak factory rear Toe rods.
By shortening the rear wheel track a greater wheel offset is required, it is advised that you have the kit fitted before measuring and ordering your new wheels!
Below measurements are NOT the exact measurement's required but only an estimated largest wheel size/offset of what MAY fit.
15 x 10" with 4.5" Backspace- 275/60 Radial 20"/22" x 10" with 4" Backspace (-38 Offset) (Both the Silver Monaro and the Red Clubsport are running 20x10" 4" Backspace wheels for reference)
If you hope to lower the vehicle then we suggest running either our Camber Boxes or Tubular Subframe to help with reducing Camber, which you can find below (This is not compulsory though)
Trailing arm's are modified factory item's that are in good working order locally sourced from wreckers and once completed are finished in a Satin Black enamel, this means that they may have small blemishes and inconsistencies. We can Powdercoat the arms and fit new wheel bearings at an additional cost, If you would like this service please do not hesitate to email us! 🙂
Shipping is Flat Rate of $195 to all major Cities & Suburbs, Remote Area's may incur an additional Surcharge.
SEDAN- When running the 100mm Kit on Split Mini tubs the fixing's for the rear Shock's can be put under pressure from moving the arm so far in, thus causing premature wear on the shock bushes.
These arms will raise the height of the car approximately 15mm, a lower spring may be required to achieve your desired look.
