These are my compiled MODs for pimping up my 42056 Porsche 911 GT3 RS. - Includes free 315 pages PDF with step-by-step building instructions. - You will need 285 additional parts to the original set 42056-1. Use rebrickable's compare feature to see which parts you need.
Now improved with new front and rear axles with anti-roll bar (see change log)!
v1.0 (2017-05-04) I started with adding all changes from Didumos Unofficial Errata. - This compilation contains some really cool changes and optimizations from the Lego community.
I took some ideas from Didumos69 Ultimately playable Porsche. - Ackerman steering allowing smaller curve radius - Additional shock absorber and improved ground clearance for front axle => Very good idea for playability! - Adding some stiffness to chassis for driving without body
Finally I optimized these features by my own: - Adding "Hand-of-God" (HOG) steering easy accessible from the dash board - Limited end positions at steering rack sliders - Small optimizations for quick and easy remove of the body (dashboard included to body; better fixture of windscreen and seats) - Some small color changes underneath the body, but keeping alle the original shape and color from the outside - Adding all my MODs to 3D model with MLCad starting from LDraw's Official Model Repository (OMR) - Create full PDF building instructions with LPub3D - Publish on Rebrickable.com
v1.2 (2017-07-08) Added these improvements: - gear box indicator, showing you which gear is selected as sugessted by DayWalker and Kumbbl - working doorlocks based on the design of el Squatter and optimized by myself. - reinforced HOG steering
v1.2.1 (2018-04-06) Bugfixes: - Added missing part "axle pin long" (11214) on page 139 - Added missing part "pin long" (6558) on page 181
v1.3 (2018-04-28) - Improved paddle shifter (smooth, easy and compact design) - Thank to Didumos who inspired me with his Improved PDK shifter. He used blue 1/2 pins to guide the yellow knob gears in exactly the right position for a smooth movement during shifting. This is much better than the original design. - I combined Didumos' geometry while keeping most of the original design and the easy to mount rubber bands on top.
v1.4 (2019-01-25) - Improved front and rear axles with anti-roll bar based on the design of DayWalker (works and looks really cool!). - And with this new front axle HOG steering is smoother (simpler design, less friction and geared down a bit)
