On the Nürburgring where the cars speed goes up to 270-280 km/h or 175-185 mph, the suspension works in its full travel range. Robert is driving daily the best handling cars in the world like: Ferrari 488 Pista, Porsche GT2RS, McLaren 620R, BMW M3, Toyota GT86 and many others. He knows how to drive and based on this we have developed our set in cooperation with Apex.  Full set includes (you can click bellow on the name of the item to view full item description):Rear Lightweight Tubular Subframe Front Caster Adjustable Control ArmsFront Lower Adjustable Control ArmsFront Bump Steer Adjustable Tie Rod Ends Front Sway Bar End Links Rear Adjustable Traction LinksRear Upper Adjustable Lateral Straight LinksRear Upper Adjustable Lateral Bent LinksRear Adjustable Toe Links with lockout kitRear Spring Wishbone Bushings with lockout kitRear Knuckle BushingsRear Sway Bar End Links66 printed pages of install and suspension setup instructionsToyota Supra A9X and BMW Z4 G29 were originally designed to provide the best driving experience for normal street use, with a reasonable amount of pushing the car to its limit. That is why it provides from factory tail-happy handling to encourage the driver to have some fun and go a little bit sideways from time to time during everyday use. The issues start to arise when we are starting to look in that car for performance, that tail-happy behavior is starting to give problems with instability of the car.The main cause for that is the rear end bump steer. In simple words bump steer is telling us how the toe is changing through the suspension travel. In stock Supra bump steer is quite significant. For example during alignment you set your rear toe to 0,11° toe in (black center dot on graph below). This is using stock camber values. Under hard acceleration Your rear end is going down, around 40mm. Then due to bump steer your toe is changing to about 0,3° toe in (blue left dot on graph below). On the other hand under hard braking your rear suspension is going up, again around 40mm. This time it will give you about -0,1° toe out (yellow right dot on graph below).As you can see, the Supra/Z4 bump steer has a significant impact on the toe during driving. When on alignment you will set your wheels to be toe in, it does not mean that in some circumstances, often difficult to predict you will be driving with rear toe out which is causing the rear end to be very lively. In daily low speeds it is not so bad, but on track usage or highways, it could be the cause of car major instability. Another issue with that suspension (5 link especially) is that it has a lot of interdependencies between its properties. It makes it very complicated to modify its setup without deterioration of its kinematics. On the graph below you can find an example of how a change of camber (new alignment setup) by 0,5° can increase bump steer even more (green line – 0,5° increased camber, red line – stock camber setup).If we would look again at an example of hard braking and rebound of rear suspension by 40mm, we are getting about -0,2° of toe out (pink dot on graph above) instead of -0,1° for stock setup (yellow dot on graph above).In some cases like going fast over a crest you can have up to 80mm of rebound which in that case would give as much as -0,5° of toe out per wheel. This is -1° of total toe out! Such big change into toe out is giving relatively a huge chance of losing grip and control of the car.Graphs above are coming from suspension kinematics software, where as an input we use suspension geometry which we gather from 3d scans of a real car. Simulation model was also validated by measurements of bump steer and camber gain on the real car. To do so, we put Supra on leveled jack stands, taken off suspension springs and disconnected the sway bars and then we have the ability to move wheels up and down with a small car jack. For measurements we have used strings, camber gauge tool and steel ruler. Measurements accuracy was about 0,05 degree for toe, 0,2 degree for camber and 1mm for suspension travel. Our measurements have shown good correlation between simulations and reality. That is why to prevent such problems we have prepared 3 suspension setup presets (Track, Street, Drag) to provide the best possible performance out of the box, for an every type of driver. These 3 suspension setups developed by us consist of our basic alignment and ride height suggestions, and what is the most important, predefined lengths of every arm, to provide proper kinematics for every designated use of car.On the graph below you can find a comparison of 2 previous shown bump steer curves (red and green lines) with a curve of our Street setup preset (yellow line).As you can see, the bump steer curve of our setup provides much reduced bump steer to prevent toe out through all suspension travel. This will give you a stable handling without unpredictable dangerous situations, which were caused by sudden transitions from toe in to toe out.Summarizing: VERKLINE goal in preparing that 3 setups presets is to improve stock Supra A9x/Z4 G29 and additionally prevent all issues which would occur due to modifying, e.g. camber or ride height to fit the car to a designated use. Our kits will include precise guide lines on how to setup the car using our wishbones and rear subframe. Used in:– Toyota Supra A90– Toyota Supra A91– BMW Z4 G29Notice: Sold for off road, track and racing applications only.

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. Under torque the trans moves around on factory mounts. Our polyurethane 85ShA mounts reduce this movement substantially helping with the drivetrain torque transfer to the shafts and wheels by removing the slop in the drivetrain.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.
