Perfect parts and fast delivery to the UK!
“Recently purchased some diff mounts for my S2, I was very impressed with the quality of the parts, and the fit was perfect. After seeing the quality of those diff mounts etc, I don’t want to use anyone else. For this very reason, I will be placing another order for even more parts next week.”

Product Description

After an extensive development and testing program we made this rear subframe available to everyone. The car was 3D laser scanned, the subframe was CAD developed, we have tested the CAD model FEA (Finite element method) and performed road going tests so you can now buy new lightweight tubular adjustable subframe.

Using the same T45 tubing as in WRC cars, our subframes provide increased stiffness, mass reduction and delivers more precise handling..

Benefits:

  • 6,5 kg lighter than the OEM rear subframe. This is 33% less weight on the rear axle of the vehicle!
  • Rear final drive moved 10 mm up (around ⅜”) to reduce loads on the C.V. joints. We’re changing its position, because if you lower the car down, the shafts are often in the wrong position. This is made to avoid early wear of C.V joints.
  • Removed rubber mounts of a rear subframe to the body and made only one mounting position. We’ve changed our subframe to be bolted directly to the chassis through smaller mounting holes. This is made to avoid shifting of a rear subframe under high overloads.
  • Additional bump steer adjustment on the subframe. You can now change the amount of bump steer moving up and down the pickup point of a rear toe link.
  • Replaced rear final drive rubber mountings with race car black polyurethane. This is made to stiffen the rear final drive and reduce its movement.

Features:

  • Much more space to access the underbody of the car.
  • Increased chassis rigidity, thanks to tubular frame construction for improved handling performance. Made from T45 (BS4T45 to BS4T100) tubing imported directly from the steel mill and S355 metal sheets.
  • We’ve kept the OEM mounting points of the wishbones, sway bar, brake line wires, exhaust system and headlight range sensor – Plug & Play!
  • Designed, fabricated, validated and tested proudly in Poland. Every piece fabricated is validated by our trained staff. Weldings are crack detected and the whole product is checked before shipping.
  • Gorgeous looks!

What is included:

  • pre assembled rear subframe powder coated black (other colors possible +50euro/usd),
  • set of steel lockout wishbone positioning shims (24 pcs.) for positioning of Toe Links (allows bump steer adjustment)(-5/ -4/ -3/ -2/ -1/ 0/ +1/ +2/ +3/ +4/ +5 mm).
  • bolt and nut kit to mount Toe Links (Zinc plated, grade 10.9),
  • set of steel lockout wishbone positioning shims (8 pcs.) for positioning of Camber wishbones (-3.5/ 0/ +3.5 mm),
  • race polyurethane mounts for the rear differential,
  • mounting bolt of exhaust system (Zinc plated, grade 10.9).

Used in:
– Toyota Supra A90
– Toyota Supra A91

T45 is a very unique seamless carbon based steel tube that has been used in many applications in different industries. It is stronger than Co-Mo 4130 tubing that also used in motorsport. It is widely used in the aerospace sector in equipment such as pilot’s seats and crew’s seats due to the materials ability to withstand high G forces without snapping or splitting. This material is a Carbon Manganese based and conforms to the full Aerospace Specification laid down by British Standards.

T45 Properties:
Tensile: 700 – 900MPa,
0.2% Yield 620MPa minimum
Hardness Test: 201min – 262 max HB or 210min – 275max HV.

Replaces:
51206-WAA05 – rear Toyota Supra rear subframe

Notice : It’s necessary to use an adjustable toe link in order to set the correct amount of toe as there is no adjustment on the subframe (replaced by bump steer adjustment). If you don’t have it already you can get it here.

Notice2: Sold for off road, track and racing applications only. Mounting the subframe may increase some noise, vibration, and harshness (NVH) in the car. We strongly advice to mount the subframe in qualified and experienced workshop.

frequently asked questions

Is this product in-stock?

We keep 100s of Verkline products in-stock at any one time. If you urgently require a product please message the team prior to ordering to confirm stock availability.

 Can I install this myself?

Installation instructions are provided for almost all products to aid with installation.

What’re the benefits of adjusting the roll centre?

Without getting too deep into it, generally speaking, the higher the roll centre the less the vehicle will roll, the lower the roll centre the more the car will roll. Talking about road cars which are adapted to motorsport, on lowered cars without adjustable roll centres (pretty much all cars without motorsport suspension) they tend to roll more than standard. Raising the roll centre higher repositions the roll centre so that there is less roll.

What’re the benefits of adjusting the camber?

Precisely setting the camber on your car is essential for optimising the tyres contact patch under load which evenly distributes the forces across the tyre. Too much, or too little camber can cause the load to be distributed more on the inner or outer edge which can lead to accelerated wear and poor performance.

What’re the benefits of adjusting the toe?

Precisely setting the toe on your car is essential for optimising multiple aspects which contribute to performance such as corner entry handling, tyre wear (heat) and straight line stability.

What’re the benefits of adjusting the castor?

Precisely setting the castor is very important as this can increase the amount of outside wheel negative camber gain and inside wheel positive camber gain when cornering, further improving the tyre contact patch, whilst running less ‘static’ camber for reduced tyre wear in a straight line.

What’re the benefits of adjusting bump steer?

Bump-steer adjustment can reduce or increase the amount of toe change there is with suspension travel.

What’re the benefits of adjusting camber gain?

Camber-gain adjustment can reduce or increase the amount of camber change there is with suspension travel.

 What’re the benefits of eliminating deflection?

Factory rubber bushes allow for the suspension to move around in ways that allow the wheel alignment to change as they load up, making your car feel less precise and often more unstable. With the Verkline spherical bearings there is no movement which results in a direct and consistent feeling.

What is the warranty on these products?
