(Mod of Mod) 2020 Koyote Altair Shadow 1.0

LS2 Swapped Koyote

  1. Shadowfast
    The new range of the 2020 Koyote Altair was recently released by PlayKoyote24, equipped with a different configurations of the 4cyl 2.0 ZOOM. The range includes the base model 2.0t, TH, TH Sport and the impressive APEX. You should check out the full range.

    The Koyote Altair Shadow is based on the TH model and is designed to bring that "growl" everyone loves.


    The Altair was kept reasonably similar to the TH with only some subtle adjustments. The standard 18 inch wheels were swapped for 19s and arches were flared out to fit in 255/40. A vented carbon fibre bonnet was added in at the front while the rear saw the addition of a diffuser and removal of the rear wing.

    Paintjob is a metallic black.

    Top Speed: 303km/h theoretical (292km/h as tested)

    The car's heavy engine meant that understeer would be a problem. The Altair was not designed to have a heavy engine and therefore adjustments needed to be done. Suspension was stiffened up and body roll reduced. The car is tuned just at the edge of oversteer and with 65% of power sent to the back (as opposed to 50/50 on the TH) powerslides are maintained with ESC off. High speed corners can have a slight oversteer characteristic but can be handled at full throttle.

    Braking is good and testing showed that after 15 laps of the Automation track, no brake fade damage was reported (the disks did reach red colour but did not remain overheated for long and braking performance was not diminished). Engine does not overheat and no internals were damaged in 15 laps driven flat out.

    Speaking of reliability and endurance. A constant spin at high revs was performed to test the durability of the engine. The coolant lasted 38s and the headgasket blew after 1min and 3s.

    High speed stability was good despite no rear wing. At 292km/h only small adjustments were required.

    It perfectly places itself just behind the APEX model in all aspects. Upon drag racing, the APEX pulls away after about 130km/h due to higher power.

    NOTE: If you want me to do any special edition of your own vehicle and include it in your range or post it separately, please contact me to have a chat.

    This car is really well built! The engine is extremely pleasant to use, and the suspensions are soft enough for the country roads, but hard enough at the same time to get a precise handling. I only have 3 complains:
    - The tires are a bit narrow for a 410hp car. Try to increase their width to maybe 250mm, it would be more realistic
    - The rear camber is to high in my opinion
    - When the ESC is on, there is no issue with the handling. But as soon, as you turn it off, your car has serious stability issues at high speed. You can try to reduce the effectiveness of the front axle at high speed by increasing the weight generate by the aero on the rear of your car by adding a spoiler, and using the aero tuning menu of Automation

    That’s all I have to say, nice job! :)

      Thank you so much for taking the time. 3 very good points in fact. I'll play around with those settings and see what I can do.
