I wanted to offer constructive (and super easy to fix) criticism on the lack of race adjustable parts, or just plain adjustable parts especially for T-series and MD, but wentward too. Those parts include: - adjustable rear final drive ratios. they are avaible for just about any car, but not those 3. they are not only needed to reach max possible top speed but also to fine tune for your needs and desires. (this one in particular has a mod which gives this, but it is last updated 25.09 and now its not only broken, because it breaks the interaxle drive shaft but also the ratios on a slider are wrong). - more long block options. most other vehicles have 6 long blocks to choose from (performance 1-3, heavy duty, ultra heavy duty and stock), T-series and MD have 2. Stock and race. Where are heavy duty ones so i can make it reach high rpm without damage and not make more power? - race adjustable governor/ECU (also with adjustable idle rpm - for every car). also avaible for just about any car, but not T-series, MD and wentward ofc. there are 2 to choose, for low rpm and high rpm, black and white. - rim and tire sizes for T-series and MD. For MD there are three wheel size choices only. tiny 19.5x6.75 with tiny tires and large 22.5x10 with two tire sizes. why not make more tire sizes, just 3 more would be a game changer. 2 for 19.5x6.75 and 1 for 22.5x10. At least one larger size for 19.5x6.75 (like 260/75R19.5 would be great) For T-series there is one rim size and two tire sizes. small tire and medium size tire. why not more? - ability to remove the turbocharger. why not? - gauges that would fit the usable rpm. MD cant rev over 2700 rpm with stock governor. what does it need 5k rpm on the gauge for? it looks broken. the same with D-series, no gauges for diesel and the redline is where the engine blows up. for T-series, this issue is with high rpm governors but the opposite, because the gauge is too short. why not add a 4k rpm gauge for T-series? and 3/4k rpm for MD and 4k rpm for D-series, there is no reason not to. - more engines for MD. There is no reason not to make the 6.9L V8 engine avaible for MD, just like 6.0 V8 diesel, or a new V8 diesel using the same sound (a little less loud) as the T-series 1100CUI diesel, but with lower displacement. and a little less important: - optional high/low gear splitter for T-series for the automatic. - overall more transmissions for T-series. semi trucks have a wide variety of transmissions, why not make more for T-series too? - adjustable weight flywheels (for every vehicle, because it isnt a thing for now). this one would be great for MD and T-series with high rev V8 because for those even the lightened flywheel is way too heavy, and for etk I-series because in it the standard flywheel is way way too light. - options for MD, T-series and wentward for different air compressors, more powerful ones. - options for MD grille colouring, the same as with T-series parts finish options. All of those could be addressed via mod but why? mods are often made amateurly and contain errors or break after updates. and those things dont require any modelling or major intervention, just a couple tweaks and make a major difference. Anyway i hope someone reads this and if you do please let me know, cause i would like to know if my 2 hours went to waste or not, so thanks in advance.
