Just ran through the Unlimited Racers portion of the career. Last of the 4 races is at Laguna Seca…but it’s not the “historic” version of the track…ya know, the one the Can Am cars WOULD have raced on during the series peak. I know the “historic” version of the track in game is crud, not really close to the proper historic layout, but c’mon…why use the modern layout?

I never really thought about the layouts of Laguna Seca until now. I think i never seen any other layout other then the 1996-present one. Well and the shorter one of the present one.

Another missed point in this series. With an “unlimited racer”, what was the thought process that led to the car initially being fitted with something called “stock” tires? And then the first level of upgrade available for an “unlimited racer” is a “sport” tire? These cars should have all been fitted with race tires initially. This is either a gross oversight on the part of the programming, or it is a bug which needs to have a support ticket.
And another oversight, there were no restrictor plates on these racers. So there shouldn’t be any need for them in the game.

There is one variation that is missing from that image. At one point, there was a chicane between turns 2 and 3 on the original layout, very small and tight but it was used to slow some of the cars down (especially the Can Am cars).

The restrictor plates would be fine if you are trying to drop below R class (for the game that is). But I don’t think it removes enough HP to actually do that.
As part of the game, yes. As part of the period correct race car, no, they don’t belong there.
But you’re right, it doesn’t drop the PI below R. You probably have to add ballast as well.

I used the M8B McLaren for this series, and about the only thing right (that I noticed) is that you can run the short or tall rear spoiler, which is accurate. We still should have the M8D with the molded in rear spoiler.

I tried the M8B via rental but found it to be a bit of a beast for me,quick as but I struggled to put any decent laps together with it.I ended up with the safe option,the Lola T163.
Before I buy a car for the featured tours,as long as there is a choice of more than one,I tend to mess around with renting the available cars before putting my credits down.
Its a pity these race series dont stay forever,its great to try different cars.

Yeah, I agree with this. I hadn’t driven any of the cars in either this week or last week’s events previously and they are great fun. This week is a lot easier - the AI aren’t as good at the courses in this championship and they are also tracks which are less prone to “congestion” at the start, which can allow the leaders to get away if you start at the back. Will be such a shame when the events vanish.

Can you tune the rentals? If not, as Ron says, the issue with these cars is they start on some form of “stock” tyre, which isn’t great, so I’d imagine they don’t feel good to drive.
I’ve built all mine to 860PI, with race tyres and full aero (using the restrictor plates as needed). Feels about the right PI for these cars/events.

Makes me question, what exactly is a “stock” tire considered to be circa 1960? Given that these tires would have all been bias ply tires. The radial wouldn’t come along until 72 and wouldn’t hit F1 until 79. So are these stock tires a bias ply model? Have they got different models of stock tires for different models of stock vehicles?
How can we find out?

What i noticed is that the stock and the sport tyres have the same stats. If installed onto the McLaren M8B, the lower spoiler also doesn’t change the stats. That is all just visual changes, but if you install the racing tyres then you suddenly get a massive stats boost.
I didn’t like the look of the car, but i liked the powerful Chevrolet engine it has, i guess it’s a Corvette engine. But i have no idea about such things.
The M8B ran in 1968, on full Goodyear race tires (best for the time frame). They typically were a full slick, but they had a large amount of sidewall flex. Forza has always had a hard time portraying these types of race cars properly. In stock (Forza) form, they are really sloppy due to soft suspensions and low tire pressures. If you stiffen them up too far, they become skittish and feel like driving on ice.
It (as many other cars did) has a big block Chevy, which could be had in a number of new cars in 1968. They started life as a 427, but I imagine they were bored and stroked beyond that.
I suspect they have one tire model for stock, one for street, one for sport, and four for race. And that’s the extent of the tire physics models. And any variance of those tire models is a direct relation to the vehicle specifications. Every tire model has the exact same base tire pressure regardless of vehicle weight. And the tire pressures are rather “off the wall” strange. But each different tire class; stock, street, sport, or race, all have the same air pressure initial setting for their specific class. Which leads me to believe, there is only one tire physics model for each tire class.
So if the Lola t163 is equipped with “stock” tires. The tire model the physics algorithm is using to calculate vehicle characteristics of road grip is the same as if the car would be a VW Golf or a Ferrari Pista. So long as these cars have “stock” tires equipped.
I don’t think that’s correct. The stock tyres for the Lola give the same PI as the sport tyres upgrade, so I presume they are some form of special car appropriate “stock” tyre.
These cars seem very strong for R class on the right tracks. Lola, Chapparel and M8B are all capable of setting very competitive times, especially in race conditions with low fuel.

That could be. But there is also a large discrepancy in the PI values when changing tires among vehicles. Makes me ask the questions: Do they have various tire physics models? Or do they just alter the tire algorithms for setting the PI values?
Or, do they just alter the wording to fit the cars?
I think they are car specific. As “mushy” as the stock tires are on the Can-Am cars, they still have far more grip than the “stock” tires on say the 1985 SVO Mustang or some other street car.
Stock tires on any of the street vehicles just seem to lose grip when pushed too hard, where these seems to “fold over” when on the limit. Tire pressure adjustments are very different between the two types of cars.
