    Hi what do you mean with "the ShortOval and Speedway ISI TGMS."?

    I've now raced a bunch of ovals (including some of @tchachalowski tracks) and i dont think the tires are right.
    I have no issue regarding grip and wear compared to ai on rc's, but on the ovals i have limited grip (on tge speedways, not the short ovals) andhuge tire wear issues (both ss as short ovals). Basicaly my tires wear within 60%-80% of the stints of the ai.

    image space incorporated ISI before studio 397 took over
    Had default open wheel tires that were used on most open wheel mods. They had a Alternative Primary Short Oval and Speedway

    Seems to be the only place to download them now.

    Could you share those upgrades? Or explain which steps to take to use these tires. I would be interested to test those

    It involves unpacking editing lines and files then repacking. Then manipulating and testing numbers repacking every time. Give me some time and I will get back to you.

    Just a quick FYI that in 1998 drivers could upshift without lifting, but still had to manually blip the throttle when downshifting.

    Here is a video from 2002 of Adrián Fernández working the pedals in his car.

    Nice catch USCTrojan,

    https://auto.howstuffworks.com/champ-car.htm#pt6

    A Champ Car uses a six-speed sequential transmission that is more similar to a motorcycle's transmission than to a typical automobile's. Shifting is done by the driver using a small lever to the right of the steering wheel:

    Another feature of a Champ Car's engine and transmission is called Shift Without Lift, or SWOL. The engine control unit allows the transmission to shift gears without the driver lifting off the accelerator. The driver can therefore upshift without using the clutch or letting off the gas, and this maximizes acceleration. The SWOL feature is also available during downshifting, but the driver must match engine rpm with the gear choice during the downshift.

    Thank you for finding this information. I believe looking at the HDV files it would just require a change to the "SemiAutomatic=1" line to "SemiAutomatic=2" as according to the annotated skipbarber HDV file that would mean upshifts are semiautomatic but downshifts would be manual. I don't know if anything else would need adjusting, @BeGee was the one who started looking at the HDV's, maybe he could advise on the way forward.

    On an other note does anybody have a picture that shows what the rain light looked like on the rear end of the Penske PC-27? I have found some that give a reasonable view of the other chassis but the one image of the Penske I could find it didn't have one fitted. Were the rain lights fitted at all times or was it only on the road/street tracks?

    I would assume on road courses only. Like Nascar, I don't think the tire companies were comfortable letting folks circulate on the the big ovals in the wet. Smaller venues, like perhaps Nazareth, Phoenix, Milwaukee....perhaps those....tracks that required braking even in the dry.

    Do we have a winner here? https://www.flickr.com/photos/39471412@N02/17235535038/in/dateposted/

    Although after zooming in, I still can't make out much. :(

    Great find with that pic!
    From what I can make out the rain light is that rectangle part that spans the rear wing supports. Comparing it to a pic I found of the car at Donington there is a difference in this area. The Donington car has a thin symmetrical aerofoil spanning the rear wing supports apposed to that rectangle shape. The fact the Donington car is in oval spec suggests that they didn't carry a rain light on ovals (one less part to replace in an accident maybe? Considering it wasn't needed on ovals).

    I don't think it works as a brake light, I presume like in F1 reactions time wouldn't be quick enough to react to it coming on.

    Unfortunately the museum closed a few years ago and the collection was sold off. I have no idea where the car is now.

    A few weeks ago I had a look on Google maps to see if I could find the factory where they were made in Poole, Dorset. I think I found it. Its amazing that 3 of the 4 chassis where made in the England.

    I wasn't able to find anything showing the rear of the PC27 from the Long Beach Grand Prix qualifying in the wet on Saturday, April 4, 1998. I think I was there that day, too. :p

    I looked through Peter Burke's SpeedCenter gallery for that race weekend https://www.speedcenter.com/archive/gallery/gallery98/03longbeach/index.html and also the usual Google Image Search. I don't know if emailing him might provide you with any images he didn't post. Does anyone else have any ideas?

    the trick is you have put the year and name of the event.

    Thank you everyone for your suggestions. I think I may have enough pics to make an accurate enough representation of the rain light. Should be an improvement over its current state anyway.

    Some progress to report.

    Redapg looked at the reynard and has given me some direction in terms of updating the physics. I am going to be testing converting to a flex chassis, suspension and steering to rf2. His guidance will be very useful and I hope we have encouraging results. Hopefully we can also make some headway on turbo and existing tires, perhaps resize a new tire model too.

    some tracks have been re-meshed and converted to the 98 layout. Thanks to a couple passionate members for providing some feedback in that regard. The focus has been on the drive with active bumps in distinct sections of the track. Each track so far has also experienced a frame rate jump with more efficient poly counts. Still have to add shadows, reflections and visigroups.. More important is the quest to get proper permission with the hopes of sharing and that is a process ongoing.

    The graphic update diggerhawk did on the Lola looks amazing. Wow!
