Suspension, Brakes, and Subframes: Restoring

Loading...

The Stripdown: Which Suspension and Brake Bits Can Be Reused?

Our meticulous approach ensures that every component is thoroughly inspected and restored to its peak performance. We started with a complete Rover Mini standard front subframe set-up, removed from the donor vehicle of our project, Bogus 2 however a thorough check, the subframe was found to be in excellent condition, making it suitable for reuse. This particular subframe is characteristic of a later Rover model.

The standard steering rack also passed our stringent quality checks however it required detailed cleaning, afterwards it was deemed fit for reuse. In need of replacement parts? Check out our full range of mini suspension parts >

Suspension and Steering Components

Upon closer inspection, the outer CV joints showed significant wear and tear, necessitating their replacement. One of the top arms, shown in the image with an alloy suspension cone still fitted, was in a salvageable state. After a detailed clean-up, it was treated with a refurbishing kit that included new bearings. 

While the lower track control arm (bottom arm) and tie-rod were serviceable, they were not reused to ensure optimal performance and safety. The rubber suspension doughnuts appeared ‘squashed’ and were ready for replacement. For more details see Page 27 in the downloadable magazine!

Reusing Front Hubs

The front hubs were another component marked for reuse. After a thorough cleaning, new bearings and ball joints were installed to restore them to their original functionality. The disc guard, however, was deemed unnecessary for this restoration.

Rear Suspension Set-Up

For the rear suspension, the hubs and radius arms were found to be in good condition and were reused. The radius arms underwent an in-house refurbishment process by our skilled technicians. We opted for new Timken-type taper-roller rear wheel bearings for improved reliability.

Unfortunately, the rear subframe was too rusty and needed to be replaced. We stock a range of Mini Suspenesion Parts and Subframes for classic Mini. Discover Now>

Subframe Welding: Enhancing Strength, Stiffness, and Handling

Front Subframe Modifications

After shotblasting, all seams on the front subframe were welded to enhance its durability, as this part of the vehicle endures the most stress. We welded two extra plates into the rear of the subframe, where it connects to the rear mounts, for additional support. Additionally, we offer the option to weld two tabs into the section that runs along the bulkhead. These tabs can then be bolted through to the bulkhead, providing extra reinforcement

Tie Bar Mount Reinforcement

When the subframe was turned over, extra fillets were visible, especially around the front tie bar mounts. Some prefer welding a fillet on the inner side to allow easier access to the tie bar, but our method ensures the mount is more effectively reinforced, resulting in a tougher front subframe.

Rear Subframe Modifications

The new rear subframe also underwent shotblasting prior to welding. Although it required less extensive welding compared to the front subframe, shorter 2-inch weld runs were used along the long edges to stiffen the frame. Need professional welding?

Final Coating

Once all modifications were complete, both subframes were powder-coated. This final step should only be performed after all welding is finished, as drilling into the coating can compromise its integrity and lead to accelerated corrosion. Some enthusiasts prefer using etch primer and paint as an alternative to powder coating.
