I drove a set last month that were almost completely worn out. I actually delaminated them on my second to last run. I borrowed a brand new set from a friend for my last run and they were much better. I like the gearing better with the taller Kumhos. I can't say much about the different driving feel since I had one worn out set and I only borrowed the new ones for the front and ran the worn tires on the rear.

Great job, Justin! Any pics or videos?
What size are the taller Kumhos you speak of? Also do you know of anyone that has used the Avon Tech-R tires? Their price looks good, that's for sure: http://www.tirerack.com/tires/Sizes.jsp?make=Avon&model=Tech+R
With the hoosiers you turn the wheel and they start turning right away.
With the V710's you turn the wheel and they seem to take a second to grip before they turn. Once they start to turn they grip at higher levels than the A3S03's but I had to turn in what I thought was a little early compaired to the hoosiers.
All info from driving the miata but others have reported the same feeling with other cars. You may also need to change your setup to get the best results when using the V710's. I changed my shock settings but I don't remember what I did to them (I think I loosened up the rear shocks about a 1/4 turn but I could be way off)
EDIT: I also ran lower pressures in the V710's because they were faster for me that way (32 in V710's, 36 in A3S03's) Both 205/55/14 on 5.5" wheel.

Hoosiers are 225/45...Kumho's are 225/50. The Kumhos have a little taller sidewall. I had to raise my rear suspension a little to keep them from rubbing. It translated to a little lower RPM overall which kept me in the sweetspot of my motor a little better without reving out second gear too bad. It helps my starts too.
I'm pretty sure apexlater is running the Avon Tech Rs. May want to PM him and ask his opinion. When I talked to him about his tires this past event, he said he'd never go back to anything else. Pricewise, they're between the Kumho's and Hoosiers. He also said they deal with heat the best, just get stickier and stickier without getting greasy.khaosman said:Great job, Justin!

congrats on your latest win justin btw my gf says hi and congrats too
well, i've just finished reading through your entire thread for the first time... I commend you on your patience and all the effort you've put in to the car! (thumb)
I was reading a couple pages back when you were having problems with the Hoosiers cording quickly thinking, you need to try v710's... I'm glad you're finally giving them a shot... I found hoosiers lasted most guys 3 events and then they fell off from there... my experience with v710's has been much better... I find that they run out of effective heat cycles before they run out of available tread... their lateral grip isn't as high as the hoosiers but its close, but in straight line acceleration or braking they will out perform the hoosiers...
I have a question for you about your brake setup. What are you running front and rear for pads? I have a P5 that is setup soley for track use (and occasional autoX), it trailers too and from wherever it goes, so it's undergone some massive lightening and is very stiff including a cage and a full suspension. The brakes were upgraded to MSP brakes, but I seem to have a bias problem. I was locking up the rear brakes with the lightest amount of pressure applied to the pedal when running Hawk HP+ front and rear. I've got a few things I want to try to fix this problem (incl reducing the amount of dampening and trying stock pads in the rear), but just curious about your setup. Right now the car is undrivable with the rears locking up because at any kind of high speed stop the rear is coming around, and you can't have that at the end of straights with walls on both sides doing a 120+mph.

Put the stock pads in the rear and give it a try. That's what I have right now along with the HP+'s up front. I can still lock the rears up first, but it is much closer to the limit of the front so I don't get any extreme bias problems. Other than SS braided lines and Super Blue fluid the rest of the brake system is stock. I rely on a lot of trailbraking to help rotation so I'm pretty sure you'll find a lot better stability with the setup I have. I've never tried the MSP brakes up front, but I can see where it would cause an issue on reduced weight Proteges.

thanks for the replies guys... I'm running a Multimatic Dynamic Setup (http://www.multimatic.com/index.shtml). They are 2 way externally adjustable (compression and rebound) with remote reservoirs that were custom built for the Protege. Huge mono tube 46mm pistons in these suckers.
I didn't build the car, and won't make any claims of the sort, it was built by a local guy who entered 3 Grand Am Cup races, and then moved on to building a Mazda 6 and RX-8, so I picked it up. They hadn't raced it since upgrading to the MSP Brakes (Front and Rear) so they never had to deal with the apparent bias issue.
I'm going to try some of your guys idea first changing to stock pads in the rear, then I'll try playing with your suggestions for the suspension. Thanks for the ideas!

I actually PAXed 12th. Apexlater PAXed 6th which is amazing!!! I went to Fort Mill, SC to race last Sunday and it was a good outing for me. The lot is very small and very tight. I stayed in 1st gear for the whole first half of the course. My rev limiter was not happy, but being right on the boiling point made the LSD hook up much faster so I was getting really good drive out of the tight corners. After a good straight the course opened up a little for the final 4-5 turns. After walking the course I was a little concerned since the weight of the Protege doesn't really help it in tight sections. The car was miraculous though. It has gotten to a point now where I don't feel fast anymore because the car is so settled and rarely gets out of shape. I couldn't be happier with the way the car feels to drive. I was watching a few cars run before me and I kept thinking to myself how quick they looked and that I was going to have my work cut out for me to stay with them. Then I would go out on course and rattle off a time that was over a second in front of them on cold tires. Project FSP Protege5 has come into it's own. With a less than exciting group of cars competeing with me in FSP I set my sights on PAX. I'm not trying to say that I'm always the FSP car to beat, but I was up against 3 Civics and a caged Suzuki Swift...all on street tires. The region I was racing in is run by Steve Rankins. If you kept op with Nationals this year you will recognize the name as he was leading his class on Day1 and eventually finished 4th at Nationals. He's a PAX terror and usually has no competition. He's been driving an STU STi recently and is a master at getting AWD cars through an AutoX course. Unfortunaltely for him, the very tight first section of the course kept the STi from getting into boost so it basically was just another big heavy car. He ran 3/10ths faster RAW time than me, but FSP has a lovely PAX index and I was elated to find my self 1st in PAX at the end of the day and 3rd in RAW time out of approx 130 drivers. I'll have another tight course this weekend, the last home event, and I'll get back with an end of the year wrap up next week.
Velocifero also did a nice video of my escapades in Atlanta.
