Late TR4. This Fast Road/Rally full suspension package incorporates Nylatron suspension bushes and spherical bearing ARB links and is supplied for fitment to Late TR4's with unequal length upper wishbones providing 3 of caster.


This package is suitable for Very Fast road cars, which also take part in rallies where comfort is slightly compromised for performance.

As later TR4's have 3° of caster already, this kit DOES NOT includes components to introduce 3° Caster.

The kit is similar to the suspension package fitted to the works TR4 rally cars and includes; 450lb/in front springs, 185lb/in rear springs and a 1" front anti roll bar with spherical bearing links which allow the front ant roll bar to work more effectively enhancing turn in. No rear anti-roll bar is fitted in keeping with FIA regulations.

Nylatron bushes are supplied for the front wishbone. The 185lb/in springs at the rear are not uncomfortable and are exactly the same as those used on the works TR4 rally cars. with these stronger springs fitted, no rear ARB is needed. For a full list of contents and a fuller explanation of out kits take a look at our information sheet viewable at the 'Product Data Sheets' tab.

Revington TR's range of suspension packages should provide suitable suspension for any application. Below is a chart showing all the fast road/rally packages relevant to the TR4. This chart will help you choose which kit is best for you. Our range is split into early cars and later cars the difference being that early cars do NOT have 3° caster so for these cars we supply the appropriate top wishbone components to introduce this.

 

Customers should check carefully if they already have 3° caster upper wishbones. Take a look at the photo and note the shape of the arms and the style of the outer ball joint. If your top wishbone arrangement does NOT look like this, you do NOT have 3° caster front suspension and will need the suitable kit for the EARLY TR4. If your top wishbone arrangement DOES look like this, you DO have 3° caster front suspension and will need the suitable kit for the LATE TR4.

 

This Photo shows the upper wishbones fitted to our adjustable upper fulcrum which is also part of this kit.
