Anybody care to guess what the trunk kit will be, rumors etc. Also tire choice?

The only rumor I heard was that the shock might be a single adjustable Koni. No idea on bars, springs, or camber plates. I did find it interesting that they removed the "non-adjustable" wording form the camber plate spec in the final rules draft.

Also, assume the spec tire will be one that's available from Tire Rack - so figure Hoosier (doubtful), Avon, or Kumho, unless Tire Rack suddenly comes up with a distributorship for Toyo or Nitto.

I'd love to see Nittos - we've been running them on the HP car and they're equal to the RA-1, IMHO. Long lasting, consistent, and quick. Everything you'd want in a spec tire in a series that's attempting to control costs.

That enough guessing for you? :)

Bilstein Sports, HR Race springs, UUC Sways (for suspension). My guess.

Tires? No idea but if I had to gamble I would bet on Avons.

Suspension? It has yet to be decided. I know that a suspension will be tested shortly for evaluation purposes, beyond that I know nothing. I would guess 2 weeks or so and we'll know for certain.

Tires? No idea but if I had to gamble I would bet on Avons.

I would think they'd choose a spec tire that actually has tread and could be used as a rain tire. The Avon is a dry only tire like the Hoosier and Kumho Ecsta V710. The Kumho Victoracer V700 (the Ecsta V700 isn't available in 16" sizes) seems like a logical choice. I've run both of the V700 offerings and think they are both a good balance between speed and longevity.

Hmm..that reminds me of how the rules are actually written.

3.A. The required tire for the Spec E36 class is specified in the Spec E36 Components list.

3.B. The required rain tire for the Spec E36 class is specified in the Spec E36 Components list.

So while that doesn't mean they couldn't just specify the same tire for both, they're also leaving the option open for different drys and wets. Interesting.

Sure wish Hankook and Tire Rack would get together.......

Since we are just making guesses, I'll throw one out there with the premise that buying stuff from TireRack is a plus:

Springs, dampers and bars: Eibach Sport-System Plus Kit, Maybe the Koni sport kit, but I'm not sure where the ARB's would come from with the Koni kit.

Tires: Yokohama A048's, Michelin PS Cups, and Victoracers all have appropriate sizes and have some wet weather capability. The Yoks and Michelin's are both more expensive but can also be durable so it wouldn't be as bad as going with Hoosiers. Not sure if the CCA is friendly with any of those companies in particular, but that might sway things.

Camber Adjustment: Crash Bolts, 96+ M3 strut bearings, Maybe some spec non-adjustable part. I'm not convinced that true adjustable camber/castor plates are what will end up being specified. Fixed top mounts and eccentric bolts for minor adjustment seem like a better fit given the direction that was taken with many of the proposed go-fast allowances.

Since I just added a giant UUC sticker to the car as a new CR sponsor, I am thinking they will be supplying some SE36 parts.

Why are you guys guessing that the Spec Tire will be an "R" Compound. Why not a street tire like a Falken or a Kumho Ecsta?? Wouldn't they last a LONG TIME!!

Toyo ra1? I talked to a few people that said they had the tires for a few years and were about 1/2 done.

Sponsor or not, BMWCCA CR has no place mandating single-source parts.

I feel exactly the opposite way. A spec series VERY OFTEN has single source parts. Ask the World Challenge Competitors where they can buy their Toyo Race Tires - it's a spec tire.

BMWCCA CR is the sanctioning body and they can do just about whatever they want with this class.

Jon, if you talk about street tires again I'm going to smack you. ;)

Ask the WC Competitors how happy they are about that arrangement. BMWCCA and WC are two completely different balls of wax.

Sure, CCA can do anything they want. Heck, they can completely rearange mod class displacements if they so desire too. Keeping the membership in mind when making those rules tends to put limits on what they should do though, wouldnt you agree?

I obviously haven't been on the forums enough recently since you lost me with the whole weather baloon thing. Hell, my little brother had to explain what YTMND and NEDM meant!

You're just mad you had to put a UUC sticker on your car :lol

Who wouldn't be? LMAO...

To me the simple definition of a SPEC class is that the sanctioning body needs to keep the supply of parts consistent throughout the nation. So a single source arrangement would be the most logical and efficient way of doing this.

So no, I wouldn't agree.

Steet Tire, Street Tire, Street Tire!!

No, a single manufacturer with a specified manufacturer's part number is the most logical arrangement. It allows people to purchase the specified part while allowing flexibility in point of purchase. SCCA spec'd Toyo so that they could get a cut from tire sales, not because they wanted a spec tire. That's the reality. It wasnt altruism or a desire to have consistancy.

It was the best I could do....

Any updates on this yet? Is there even a firm timeframe for a decision or is this a 'it will be done when it is done' type situation?

My guess is Nokian NRWs, that way when it snows at Mid-Ohio you're all set! :cool

They don't use them, then. I get better life from Hoosiers.
