This is a project I've taken up personally to delve into the absolute META of Street Legal Racing: Redline. Essentially, the time consuming, Min-Maxing that everyone will do to so degree in this game; However, I'm going to be looking at what I consider to be the META of this game; DTM Chassis.

Now, to those who do not know, you can buy car chassis from the catalog; The Einvagen 1xx Series, Emer Nonus, And the Baiern CoupeSport all have a DTM Variant available.

This is basically going to be a comparison; Three Einvagen 1xx Series; One a E 110 GT, bought fresh from the catalog; The Second, a E 140 DTM, also bought from the catalog; The third will be an E 110 GTK bought from the used car lot. Essentially, this vehicle will serve as the control. I will essentially not be touching it until thorough testing has been done in comparison to the other two models, then we'll work in the scientific method with that piece and see which aspect makes the biggest difference (Engine work, Suspension Setup, Tires, Weight…).

The overall test is generally between the E 110 GT and the DTM Variant;
The reason I chose the 110 GT and not the 140 GTA, for example, is because the 110 GT is the lightest raw chassis of the Einvagen Family; Oddly enough, this also includes the DTM Chassis, which is actually the heaviest Einvagen Chassis.

For those who care, the actual chassis weights (No other parts; Bought fresh from the catalog) are:

110 GT: 775 kg/ 1705 lb
110 GTK: 804 kg/ 1768 lb
140 GTA: 795 kg/1749 lb
140 DTM: 1080 kg/2376 lb

Seeing these numbers, I've decided to use the Lightest chassis in comparison to the DTM.

To make this clear, both the DTM and the 110 GT will be using the exact same parts; The only differences will be the body, Chassis, and of course, The Engine. Both the main test Vehicles will be using V8's; The DTM will obviously be using the Lama Performance V8 DTM Engine Setup, and the 110 GT will use a comparable setup (As well as using the engine from the DTM Variant at some point, as well).
The 110 GT has been edited to support the engines using Sparky's Editing Tools:

For the record, it does work in the Steam Release of the game and is pretty straight forward. An overlying purpose of this test is to see whether the DTM is worth the price, especially in comparison to a V8 Swapped 110 GT.

Everything will be documented and parts lists will be given for exact details as to how I go about the testing.
The testing itself will include Acceleration tests, Hot Laps, Top speed, and a few other tests I will work in regarding Handling and other aspects.

Note: The third Einvagen 110 GTK will be the control for the majority of the test; What it will become later is, essentially, the un-edited test subject. First, acting as the baseline for the vehicle you may have bought at the beginning of the game (It cost $18,562, Runs, Drives, and is a very capable machine) and basically be just that. After that testing is done, I will build it up with Einvagen parts and see how fast it is in comparison to both the DTM and the V8 110 GT.

If you don't know, you can find DTM Chassis Cars on lots. I've only seen one in the Used Car lot; It was an Emer Motorsport Nonus DTM in (From what I could tell) Very decent condition. This was before you could buy access parts for them, and ever body panel was intact, painted the same color, and it included an engine. However, it's price was near $1.5 Million. Odds are, you'll be buying your DTM from the Catalog (Or bring it in with cheats, if you wish)

For those that don't know, DTM, as a racing term, means 'Deutsche Tourenwagen Masters', or 'German Touring Car Masters'. One would expect it to be the most performance oriented variant possible for the car, though the initial weight is staggering, it is understandable; It is meant to be safe above all else.

I am predicting the DTM chassis to overcome the weight difference with the engine that it seems only the DTM vehicles can use. I'm interested to see how the handling will differ, but i suppose only time will be the tell.


Also, This guide will not be a "All at Once' deal. At the time of writing this section, I have only purchased the chassis, recorded and compared specifications, and theorized about what setups to use for the Cars; This will be an on-going project and it will be a time consuming one.

Do realize that a good portion of this project is subjective: I will be using running gear parts i know and like; The Engine setups may not be the single most powerful setup possible, and so many other factors will basically boil down to my opinion.

Overall, The DTM is a wild beast to tame; Certainly capable of much more in terms of handling and maneuverability than the others, but It requires a very steady hand. The cost to repair any mistake is astronomical, and, if you try skimping out while building the engine (Use anything other than LAMA and Prime DLH parts), the Power suffers immensely. The engine I built, though weak at its peaks in comparison to the 110 Custom Engine, had a solid Power Curve, as well as a much Higher redline; Both of which attribute to the higher top speed in testing. The largest downside to the DTM engine is that what you throw together initially will likely be as strong as the engine gets; If you treat it right. Unfortunately, you cannot Supercharge the Lama-Based V8 engine. To be literal, you can put the supercharger 'on' the engine physically, but you cannot connect the pulley required to run it onto the Lama Crankshaft, so all it will do is add weight in the best scenario.

The 110 GT Custom is The amazing Step-Brother. It isn't quite as fast as the DTM, but it is more user and wallet friendly and still capable of amazing Handling statistics and mind blowing Speed. It does initially accelerate faster than the DTM (Likely because of the higher peak in Power), though, in comparison to the DTM engine, it lacks a level power distribution as well as a decent redline. I don't have a doubt that the 110 Custom couldn't go faster than it is with the right Transmission, but the DTM engine would be right there, beside it… Assuming you want to keep the car looking 'normal'… The largest advantage is the ability to Supercharge this version, which would, without a doubt, get it going much faster than the DTM could ever dream. The largest downside to this option is that unlike the DTM, the GT Custom holds the V8 engine far higher in the bay (You can adjust this with Sparky's Editing Tools, but not only would you more than likely ruin the ability to use any other engine in any Einvagen 1xx family, we're going for simplicity here) which is likely the reason for the tendency to tip, as well as pulling the front wheels off the ground.

The final Product of the 110 GTK was very surprising, and comparably cheap to the other options, though, the largest downside is, in my opinion, the lack of adjustment. The final product is as posted Beforehand and reached 280 KPH, which is very respectable; But you are unable to adjust the Transmission or the 40-60 Front-Rear split center differential. In comparison to the DTM or the 110 GT Custom, it is a very drastic step down in every aspect. That is definitely not to say it is useless. It is still a very viable car, and the most reasonable and user friendly vehicle out of the three options, and, bear in mind, I haven't put all that much testing into optimizing the performance or anything beyond putting a decent engine into it.

Personally, I would prefer the 110 GT Custom. The cost difference between its setup and the 110 GTK is a large sum, but the performance increase is astounding. In comparison to the increase in cost to get the DTM Variant in comparison to how much faster it is than the 110 GT Custom, it isn't worth it. One wrong move and not only could you lose the $16,000 front bumper, the chassis is just as expensive to repair if you dent it. The Engine, though not as expensive in comparison to the body, is still a hefty sum if you end up damaging or losing it entirely. Not to mention, even if you do not care about how the vehicle looks (If you're running around with absolutely no body panels and have no intention of adding weight), the GT Chassis is still lighter than the DTM by a large amount.

I would argue that the DTM is one of the best vehicles you will come across, simply for the fact that it is capable of so much, but you want to drive it carefully and not risk having your wallet emptied. The ultimate test of nerves, as well as the epitome of the phrase 'Risk & Reward'. It is certainly a fun vehicle to drive, but If you are dead-set in building one of these machines, I'd highly recommend 'Saving' the car and driving it around to get used to how it controls; Otherwise, you'll bankrupt yourself trying to keep it in working order. Though i will eventually own one of each available, they will likely be nothing more than trophies; Driving them only on rare occasions.
