What is a "touring car?"

[Z3_GoCar]

The vast majority of SM guys in STL out here are there because they won't get enough points to qualify in SM for the Runoffs. So to qualify for a class, any class, they can race in and earn a decent number of points and qualify for the big race that the other class they're going to race in.

In addition to removing the allowances that Eric had to make STU more cost competitive, I'd add get rid of Forced Induction or at least throw another 300 lbs on a given size TIR. When you make both more power and torque and weight 200lbs less, there's something wrong.

A Touring car has 4 real seats. The 2 seat 4 seat performance difference is mostly the sum of windshield angle and vertical CG ratio to track.
The CRX/Civic perform about 100# apart as do the VW Scirocco/Rabbit. Both cars are about 6in lower than the sedan version and turn better as a result.
For the ST cars there are no direct comparison RWD cars. (Lotus 7 and Lotus Cortina? ) Maybe the Miata and Ford escort GT?
The Miata are very well driven,and can out perform their expectations due to the best drivers trail braking to the apex. Not many FWD cars can do that.
The miata can sustain very high lateral grip values that taller cars cant due to overheated outer (front) tires. The notes about WGI with breaking parts and high G loads is common in the T5, T6 and toe turns- the banking adds a lot of loading that the Miata loves. 1.5-1.6 is common there. The feel of the Miata is very solid, while the sedan is more like HS I'm gunna punch that outer tire wall evry lap.
I dont see why the class exist either.

We all know Miata's are a fantastic car where the sum of its parts create a supurb racing platform. Isn't it going to be true that ANY multi-marquee class racing the miata will win all things being equal?

Isn't the only way to handle this situation, regardless of class, to dis-advantage the miata in some means? (weight, restrictors, etc?)

I don't see STL being any different that ITA, etc...

Already happening, no? 5.5% more weight than a FWD car with double wishbones and 8% more weight than a FWD car with struts.

2731lbs for the 13B powered Miata
2635lbs for a BP powered 1.8 Miata
2430 for a 1.8L double wishbone FWDer
2370 for a 1.8 strut FWDer

All on the same 225 width tire.

The question is simple, are these weight differences sufficient given what we are seeing in the results? What do you think Jeremy?

I personally don't think 5.5% is enough difference between a FWD and RWD car with double wishbones.

I think we need a Miata multiplier! If Miata, then add an additional 3% to the calculation (or something....) Edit 1: I am just making up numbers and have ZERO data - Just throwing something against the wall

Edit 2: And I say that being out of racing for 4+ years and no longer having a dog in this fight or honestly caring.... I simply think that the car is a fantastic package and not sure how to equalize apprpriately...

Edit 3: 5.5% may be fine for double wishbone cars that are RWD and not a miata. Its the specific car (miata) that seems to be what breaks all the logic.

There are plenty of cars that can handle as well as a Miata given the same weight. 3rd gen RX-7, Porsche 968 (and not DW's at 4 corners either).

I think 200-300lbs difference is a lot given the same size wheel/tire. The 13B car is almost 400lbs more than a strut FWDer. That's a bunch. Given the WGI results between the Miata and the Civic, I'd say it's dang close if not there for now.

Even if we were to assume that's true - and it's absolutely not, simply because you were not there and all you have is a results sheet which doesn't tell the whole story - what about everybody else in the class...? Is the class to be limited solely to the best example of RWD sports car available versus the best example of FWD strut car available to use today*?

Given the evidence at hand, I suggest you've just offered excellent supporting anecdotal evidence for slowing down a couple of front-running cars.

*As the Miata is to small 2-seater sports cars, the FG Civic is to FWD strut cars. When Honda decided to ditch the wishbone suspension for the Civic, they didn't just throw some crappy struts on the car as they did with the RSX; they really did that car right. The suspension geometry is as good as it gets for struts, to the point where many pro teams did not even bother moving pickup point and relocating ball joints as allowed by the rules; it just wasn't needed.

A lot of people think that car does well because of the very good ~200hp K20Z3 (which has to de-cam and run a restrictor for STL); that's certainly part of the equation. But that chassis is a super package all on its own. Bob Beede actively moved from a 1.8LGSR engine in a '99 DWB Civic in 2012, to a lightly-modded SSB FG Civic Si in 2013 and thought it was the better package.

The ongoing "Miata Penalty" will continue to vex all RWD cars. In the same vein, it's quite possible that FWD strut cars may eventually suffer the "Civic penalty" (unless we choose to slow down those specific examples instead...)

Regardless, the CRB will continue to adjust vehicles as needed to ensure reasonable parity within the Majors program. And since the class is based on general mechanical characteristics of the vehicles versus line-item classifications the CRB will, no doubt, continue to create and adjust these characteristics as needed to ensure that direction.

Earthbreaking, ground shattering logic at work here, how come we've never heard that suggestion before [/SARCASM]

[Jeremy Billiel]

Clearly JS154 you know everything... So what is your recommendation?
