#1. Kumho ECSTA V700: weird wear groove - from Todd C. Merrill
Top
Date: Thu, 1 May 2003 21:57:05 -0400 (EDT) From: "Todd C. Merrill" <tmerrill@mathworks.com> Subject: Kumho ECSTA V700: weird wear groove I corded a Kumho ECSTA V700 tire today...on the outer-center blocks. :( I found that a curious place for a tire to cord. (See footnote [0].) I found these two reviews on TireRack's site: Vehicle: 2001 BMW M3 Coupe the ecsta v700 needs to be heat cycled and then aggressively rotated and flipped in order to maximize tire wear. If you do not, you will develop a "groove of doom" on the second rib from the outside tire. Vehicle: 2002 Subaru Impreza WRX Sedan Only major drawback is in the ware department. They need more air than you think they do. If you dont have then pumped up, the grove of death appears at the second radial grove in. (All misspellings the reviewer's, not mine.) Mine were shaved, but I've seen this weird wear behavior with unshaved ones, too. My pressures were within the recommended pressure ranges, too. This was dry day 4 on them--how "aggressive" does the rotation and flipping have to be??? Anybody else seen this? What causes the problem? Any solutions? I like this tire in general, but this weird wear pattern is killing me. Or more precisely, my wallet. Until next time... Todd 1998 BMW Dinan M3 coupe BMW CCA member, Boston Chapter --- [0] If you look at a picture of the tire: http://www.tirerack.com/images/tires/kumho/ku_ecsta_v700.jpg call the 4 sets of blocks across the face: outer (wide) outer-center (narrower) ** inner-center (narrower) inner (wide) ** this is where the tire corded. All three of the remaining "good" ones have a serious valley in this area. The outer or inner blocks have lots of usable tread left. :(

Jim switched to Toyos and Wayne is running Pilot Cup Sports. It's a known issue with that tire...that and blistering and chunking. You should think that the tire is overinflated, but one of the chief instructors said that it was actually underinflated. He said to call up Kumho and talk to them. Chester --- "Todd C.

The tire sucks. Their "support" (I use that term loosely) is fairly non-existent; particularly upsetting since this happened on the race car and Kumho is supposed to be a CCA Club Racing sponsor. Repeated emails & phone calls regarding trying to find a solution went unanswered. >Any solutions? Use another tire.

That is first. If you really want to build a race car and go racing, the E30 M3 is a very expensive way to go long-term. You can go just as fast or faster for less money - especially in the long run. I also hate seeing a nice rare M car butchered up as a race car since they are so rare and such nice cars. Anyway, if you want a real race car, I'd opt for the E36 325 or something along those lines instead. But if you are looking for a unique, fun, race-inspired car that is well suited to DE's, than the E30 M3 might be just the ticket. I went through a similar decision point and almost just determined that I would use my E36 M3 as my track / DE car in addition to daily driving chores. But in the end I decided to convert my '91 Corvette into a full race car - roll cage and all, no longer street licensed. I'm just starting that conversion now. I want a safe and fast car for track events that I can eventually take into real racing venues. I also already have a car trailer and rig to tow it with - part of the major start up cost to go real racing if you don't already have that. This car was cheap because it already has much of the work done to it to make it a good track car and I would not be able to sell it for much anyway. That way I get to keep my M3 as a nice street car and not worry about trashing it on the track. Although, I am sure it will be out on the track at least once or twice a year - but not on race tires / brakes like it would have been if it were my only track weapon. I'll just drive it there with the normal street set-up and not go quite as hard as I do in my track car. But that is a personal decision each of us who love to track cars has to make.

#7. Helmets and height of helmet..which are "shorter" - from Msebmwman@aol.com

Date: Fri, 2 May 2003 02:07:24 EDT From: Msebmwman@aol.com Subject: Helmets and height of helmet..which are "shorter" All; For anyone that has tried on a bunch of helmets in their cars, is there any particular brand or model of helmet that you have found to be "shorter" or not as high above the top of your head as others? I'm a tall guy and am trying to find a helmet that gives me a little more head room in the car. When do the Snell 2005 rated helmets start coming out? Thanks, Marc 95M3

I have a Bell M3 and I just barely have fit in my M3 with sunroof even though I am short. In fact, I would discourage most people from using Bell helmets because I think they tend to have very small eyeports and fit VERY snug. If you are at all claustrophobic, Bell may not be for you. Try any helmet on to see how it feels on your head. Headroom might be a secondary concern. Good luck! Lowell Seaton '95 M3 BMW CCA #131505

The Kumhos do not withstand the heat build-up that a 20 to 30 minute spirited Advanced Driver Training session can deliver. A 20 to 25 percent initial savings is very bad economy in comparison to the Toyo RA-1 if the Kumho only lasts 1 day vs. the Toyo's 8 to 12 days. Solution, drive slow and carefully on the Kuhmos or switch to Toyos. Gerry > > From: "Todd C.

After 18 laps at race pace the current Ecsta V700s were toast. After 22 laps (typical SCCA National length) the new compound was wearing well, enough to be reused again and still turning the same lap times. Supposedly mid Summer the new compound will be out. At the last race, a SCCA National driver told on of the guys I drive with that he ran Victoracers V700s all last year because of the same issues. The greater the slip angle the more accelerated the wear with the current compound. Jeremy Lucas 95 M3 (next set of track tires will be Toyos)
