2020 Toyota Supra Track Day 2
Streets of Willow Springs - Fastest lap time: 1:25.36
(Reference time: 1:22.43 in my S2K naturally aspirated with aero)
Modifications:
H&R Lowering Springs
Toyo Proxes R888R 265/35R19 & 295/30R19
(Stock engine and brakes)
Streets of Willow is a fairly tight and technical track requiring finesse and smooth applications all around (steering, throttle, brake) to tie together a decently fast lap time. There are a few high speed sections and transitions that will definitely test your courage. The Supra seemed to be a perfect fit for the track as it shares the sharp steering qualities similar to a S2000 (well not quite, keyword similar) and a healthy amount of power even in stock form. We didn't have time to upgrade the pads from stock, but we did install a set of H&R lowering springs as I was general curious as to whether or not lowering springs would actually provide a noticeable improvement in roll, especially in mid to high speed sweeping corners. To my surprise, the H&Rs did a fantastic job both on track and on the public streets/highways.
On Track Performance:
A few noticeable improvements the springs gave us were:
1. Lower ride height (very important)
2. More camber. Fronts were able to achieve -2.2 to -2.3 deg camber (matched rears), which translated in improved turn in/mid corner grip, as well as better tire wear (as the tire was not rolling over the sidewall nearly as much as it did with -1.8 deg camber).
3. A notable decrease in body roll. The stock suspension caused the Supra to roll more than ideally, giving a slight "floaty" feeling in high speed sweepers and transitions. While the overall car was still planted thanks to its' great chassis, the softness was definitely not what you'd call confidence inspiring in certain sectors of the track.
Streetability/Comfort
I drove the car to and from the track approximately 120 miles each way and can honestly say that the springs did not add much, if any, harshness or discomfort on the road. In comfort mode, both the H&R and factory springs felt nearly identical in my opinion, whereas. Lowering springs are definitely not the end all solution if you are looking to maximize lap times. However for the daily driver or average weekend track day goer who still uses their Supra as a daily driver and wants to maintain the electronic suspension options, the H&R's won't disappoint. The next step for our Supra will be KW V3 (or Clubsport) coilovers with the Electronic Suspension Cancellation kit in a few weeks to come.
Before leaving this on a note of spring "praise" lol, it is very fair to mention that upgrading the stock brake pads should be at the top of the list when going about track preparation. Brake fade is apparent after a few laps, and progressively worsens as it gets hotter (Especially on the second track day, even with Motul RBF600 fluid). The next pad upgrade will likely be the CSG C2 (Race) pads.
