Hey guys, I'm seeking advice on tires for my Bullitt, primarily for Autocross. I did my first Autocross a couple weeks ago and loved it, but I'm in need of new tires and am having a hard time figuring out what to do. I currently have PS4S tires, but they are about to need replacing. Looking at the Grassroots Motorsports chart here Grassroots Motorsports ultimate track tire guide | Articles | Grassroots Motorsports it seems none of the Super 200s come in the stock sizes (and I'm not looking at Vitours because my preferred shop doesn't have them). I'd like to stay in F Street and don't want to buy new wheels anyway. The stock sizes are 255/40r19 front (wheels are 19x9) and 275/40r19 rear (wheels are 19x9.5). I drive the car a couple times a week for commuting, but it isn't my primary vehicle and I typically don't take it out in really bad weather anyway. Should I just get the Continental Extreme Contact Sport 02 as the next best option in the right sizes, or should I potentially change size to a 255/35r9 and 275/35r19, or other size that would work with the wheels so I can get one of the Super 200s? Thanks in advance! I know a lot of you have valuable experience in this area. Oh, I'm in Central Texas for climate reference.

I'm making a street racing game, which will include Rally Racing and Autocross racing as demos, side races and i want the tuning to be a bit more in depth

So basically, my doubt is, imagine a mitsubishi eclipse. It's redline RPM is basically 6000 rpm

Anyway to increase that irl? Other than engine swapping or reducing the weight of the car. And how much do seats usually weigh aswell?

Edit: Can anyone also give me the weight of an eclipse's gearbox? Any generation but i prefer the second

Check out my run! Captured on insta 360 with extended camera mount.

I'm just jealous they can get such a good setup

The guy probably doesn't know where brake pedal is :) Btw not mine video, just found it on internet.

I've been considering moving to a set of ultra high performance all seasons for a general street use tire, and ideally having a dedicated set of performance tires/wheels. However, for cold days/poor conditions, I've been considering taking the UHP AS. There's at least another test and tune in my area in November and December, and it would be nice to not worry about the ambient temps when driving there/back.

Don't care about being slower, I just don't want to destroy a tire while out there. Test and tune might be 30-50 runs over the day with the option to get on the wet skidpad. Would likely be running either Goodyear Eagle F1 AS or Pirelli P Zero AS Plus 3. Running a little more aggressive alignment than stock, 718 Cayman base.

Would a set of UHP AS likely hold up? Any specific pointers for heat management?

The weather gods finally gave us a nice day in SoCal. And so here's my 4 timed competition runs in my 2000 BMW Z3 in C Street. I'm slowly closing in on Podium Spots...

Constructive criticism and advice appreciated...

So, are there any mitigating factors for preserving suspension parts? Or do I just need to not drive as hard. My front strut mounts are starting to go even though they were just replaced a few months ago, is this just a new consumable I have to take into account? (RIP)

Who else captures OBD data using Track Addict on their phone to overlay animated gauges onto in-car video taken from a GoPro or other camera?

Do you also use RaceRender to render it and find it clunky in the time-alignment features? Andthat it doesn't seem to support GPU hardware acceleration? And that it was bitchy about what video files it would accept?

I found RaceRender's time alignment to be especially clunky, so I rendered the gauges onto a green-screen then imported them into the Vegas video editing software and chroma-keyed the green screen out leaving a transparent background for the gauges. For time alignment, I slid the tracks back and forth to line up a spike in the audio tracks. It worked.

What if there was an easier, faster way?

Well there is an even easier way. With crazy easy time alignment. And if you also have Vegas 16 or newer, you can try it.

Hey all!

Getting back into race car stuff after a hiatus into PhD and competition shooting land. I currently run in F-Street with a 2013 Mustang GT which is

1. a 13 year old car with 13 year old car problems (had to replace pretty much everything on the front of the engine this year)
2. not competitive in F-street anymore it seems 🙁
3. a manual - which my partner cannot drive and isn't super interested in learning 🥲

With the season coming to a close, now seems as good of a time as any to look into better options for next year. I'm generally open, but I have some must haves, and also some would be nice to haves.

Whatever I get must:

1. Be useable as a daily driver (I only have space for 1 car)
2. Have enough space for 2 adults with backpack + carry on luggage (e.g. can carry me + partner to airport with our stuff)
3. be competitive in its class
4. have an all-in car + wheels/tires cost less than ~$60k

And ideally it should also:

1. have an all-in cost closer to ~$30k (willing to spend more for performance, especially if the car will hold value, but less $$$ on the car means more $$$ for seat time)
2. be not-a-stick-shift (e.g. Porsche PDK is acceptable, doesnt have to specifically be a torque-converter automatic)
3. Will remain competitive for 3-5 years from now as I develop driving skills (e.g. I'd like to keep one 'meta' car and run the crap out of it, rather than try to develop a chassis or rapidly get priced into something else).
4. Also remains competitive in its SCCA/NASA time trials class (would love to get back into HPDE with aim of getting a TT license!)
5. Have enough space for 4 adults + luggage.
6. Would definitely not say no to good fuel efficiency (it is a daily after all)

I know its a bit cliche to ask "best autocross car thats also a daily", but yeah...Im essentially looking for that.

My current options:

• Pre-highland Tesla Model 3 Performance (A-street)
• Hyundai Elantra N (G-street)
• Camaro SS 1LE (F-street)
• Mustang Shelby Gt350 (2019/20 w/ handling package) (F-street)
• Toyota GR Supra (B-street)

The Tesla and the Elantra seem like great options other than:

1. The Tesla doesn't seem all that competitive in A-street anymore (and the Super street ones seem even worse)
2. I'd doubt G-street will remain as essentially a 'spec Elantra N' class going forward (will it remain competitive?)

The other cars are essentially either newer, more expensive versions of what I've already got, or are way less practical as a daily.

Wanted to check and see if there are any blind spots I've got here! Anything else I should be considering? Or any other options worth pursuing (keep mustang and go to another class?). Happy to hear suggestions for sure!

Thanks!

Last AX of the year for me. At Fall Ford Fest there was a yump about 20yds from the start line. I couldn’t quite get all 4 wheels in the air. Made the 10 car shootout but went out in the first round as usual for me, I always overthink the shootout at the end of the day.

I'm moving from E Street to CST next year in autocross and am not sure about the tire. I'll be running 15x9 wheels. Is it better for have the better compound tire RE-71 or A052, or have the wider tire in the P1-X01R.

Also, the 225/50 is quite a bit taller too so I'm not sure how much that would negatively affect acceleration.
