SCCA ESP Thread

Assuming you buy them brand new how many events (4 runs 50-65secs each) would you expect. I know its all relative but the general consensus of 200TW tires is AT LEAST a full year (12 events) and most likely closer to 18. Just wondered if this is a realistic expectation for R compounds as well.

Using the camber bolts, (entirely new to me) do you need to adjust them each time before the event and then back to 0 degrees after to avoid wearing out your road tires?

Sorry for the stupid questions but I appreciate the education!

if you're concerned with tire life/cost, it'll be tough to beat a street tire. i also have a set of 315 Rival S to run locally in CAM-C for just that reason. i don't have enough experience with tire wear on the S550 to make any conclusions, but i fully expect my rivals to outlive my hoosiers. by how much, i can't be sure (check back next year i'd imagine!) - but i know of a few national AS vettes local to me running the BFG past the wear bars with many heat cycles that are experiencing similar performance to new; you'll be hard pressed to see that kind of consistency in the life of a hoosier.

i've been running -3.5 on my stock pirellis for DD with no abnormal wear after 2k miles since installing; as dick mentioned, toe is the culprit to inside wear, not camber. and i'm even running 1/16th toe out, too.

as for a rear 9.5 fitting up front - i've got 3" ARP studs and 20mm spacers (along with a couple sets of 5mm hanging around). when i install my adjustable swaybar endlinks this weekend, i'll test fit the rears up front and let you know what works. of course, you're going to get more width from a 295 hoosier vs. a 275 pirelli, but it'll give you some idea of what you're working with.

are vorshlag plates plates available?

i'll let you know after i get off the phone with them later this afternoon. in their words, when i pinged them on monday:

"I got tracking information on the shocks late last week, they are on the way! The camber plates have been machined as well...mostly. There is 1-2 more operations before they are completed. The run of S550 camber plates was made specially for your order, and we have pushed back other components from getting milled to make that happen. We will be finishing those plates today/tomorrow so we should be in good shape to get you something by the end of the week, hopefully. Many moving parts to get this to happen, and we are thrashing to do so."

i'm sure jason will chime in here at some point if he sees this, too - i definitely don't speak on their behalf, just relaying useful info. don't hold them to anything, they are very busy and i really appreciate that they're giving us S550 guys this kind of attention so early in the release cycle

You rang?

I think there are a couple components to the S550 plate that are being plated. Once finished we will be shipping the first couple sets people are waiting for, then photographing the production versions and adding them to our site.

As far as spacers, camber bolts and 18x11 wheels, the 18x11 is a very tight fit to the body of the strut when the spindle to strut interface is pulled as far as possible into the positive camber position. Using a camber bolt there will require a spacer. We prefer to achieve our negative camber with the camber plate.

timely! i just got off the phone with terry; he told me what you reiterated here. can't wait to get these on my car, been a long time coming!! after last weekend's botched experience on stock shocks, lowering springs and dying, overtired hoosiers on undersized wheels, i can't wait to run this car properly prepped @ packwood nt & pro! well, absent real rear springs and the articulators of course. can't have everything all at once, i know ;)

didn't mean to imply an 18x11 w/ bolts and spacer would fit - i already tried that, in absence of plates, to no avail. i was only speaking to the 19x9.5 stock rim, which i think will work for the cost-conscious poster above. you won't ever see a wheel that skinny on my car at an event! thanks again to you and the team at vorshlag for being a crucial part of my journey to full preparation for national ESP autox competition

Regarding running Street Touring at the National Level. Good luck because it will take a lot of it. Better off either staying in FS or going to ESP.

Edit to add: Ford has the offset and backside spacing info here: http://fordperformanceracingparts.com/parts/part_details.asp?PartKeyField=25186

I've been running STU the last few events, and have been a mix of on the same second to a couple seconds off, but with crap tires.

I think with coilovers and appropriately sized stones(285-305), I think I'd be right there with the local guys, but regionally vs. Borg, probably not so much. Giving up the weight we do to the vette, I don't think it could happen, even if we could get past the boost buggies.

Boost buggies can be a major issue in Pro Solo even against the Vettes. If winning at the National level isn't a priority then STU makes sense compared to running Hoosiers in ESP, especially if tire changing at events is not a goal (been there, done that, I was decades younger then . . . ). The Bridgestones are pretty decent highway tires, at least with stock suspension, so they should be viable in ST also.

According to an FS BMW driving Bridgestone employee a 285/35x19 is due in the US very soon. I got the impression that anything bigger is not in the works but I really don't know since "not relevant to me

The Bridgestone rep told me the same thing at the Texas champ tour.

I've been putting off buying tires to wait for those, just to run CAM at Nat's.

Next year After Nat's I'll decide if I really want to go ESP, or S/C the car and just continue to have fun with it in CAM and OUSC events. It's been a weird tire year for big cars. Hopefully that will sort out some by next year.

I think the S/C will end up cheaper than ESP prep by quite a bit.

What tires to put all power to the ground?

 

[murphyslaww]

Hopefully a.Bridgestone bigger than a 285.

Rumor I heard was that a 305/30-19 re71r was coming next year....which makes me very happy.

i have forgestar cf5 +56 18x11 w/ 315/30R18 hoosier A7 and enkei pf01 18x10.5 +38 w/ 305/30R18 hoosier H2O.

Does the Enkei pf01 18x10.5 fit front and back without spacers in the 38 offset? Also, these do clear the PP front brakes?

Thanks

with this setup, yes and yes. can't speak to others, although i've heard that jadrice test fit an 18x10.5/315 A6 setup without issue; unsure if he had to use a spacer up front or not though (it'd be a very small one if so, 5mm or less).

That being said a 305 tire in the front should clear just fine then right?
