As the new owner of an '06' Boxster with PASM, Sport Chrono and the 18" wheels (and all of 700 miles on it) I'd like to share my experience with the those options: 18" rims with in Sport mode: On the back roads in rural Ohio, while the Sport mode does tighten things up handling wise, it is not the mode that I'd care to do any extensive driving in except at the track. Not punishing but your head is moving up and down with the undulations of the road. In normal mode, these undulations would be barely noticable. On a smooth highway there probably wouldn't be much difference between the two regarding ride quality but on typical midwestern roads the sport setting would get tiring after a while. 19"rims standard suspension: We drove a demo with 19" rims on city streets and while they felt good on good pavement, I'd be concerned about how they'd fare on pot-holed streets--not much sidewall. Also, the standard airpressure goes up to 32lbs in front with the 19s, which will protect those rims a bit more but also firm the ride up a bit. Sport Chrono: We haven't tracked this car yet, but I enjoy the more responsive throttle settings even on the street. The stop watch function looks problematic for auto-x but I'm thinking you could probably use it occsionally during a track session just to get a feel for what your time was. It would definately work best with the PCM but that a lot more $.. Don't forget the sport seats for $700--they are great!
Uncle Bob: Nice wheels; One question--why didn't you go with a set of stock 17" rims with a 50 series tire instead of the wider set? From what I hear, a narrower tire works better in the winter.
Did you get any money off as a credit for the old engine? I'm sure there were usable components on the motor--maybe even the block. This raises an other question for this board--has anyone had an 986 boxster engine repaired and/or rebuilt at your dealer, instead of swapping new motor for old? I ask since most of the engine problems I see posted on the various 986 forums seem to result in a plug and play approach to engine repairs, which is extremely expensive as you found out. Best of luck with the new motor.
Rich: We had a '99' and traded i t on an '06' recently and am happy to say it was the most reliable car I've ever owned; no problems what so ever. Having said that, there were a number of boxsters that had the the "pressed in" cylinder liners done in late'98' to roughly 2/99 production. There was a problem with the subcontractors machinery that provided the blocks at that time, so Porsche made a decision to use blocks that didn't meet their speck by pressing in cylinders liners. Apparently it didn't work all the time and their were lots of failures of cars with these engines; Porsche supposedly has replaced them without an issue to this point. The PCA tech section has some in depth articles on this issue. If you have a car built from roughly 10/98 to 2/99, this might be an issue. The PCA article said it that if there was a problem, it ususally occurred soon after the customer got the car--within 10k miles. Having said that, I read reports of owners that have had failures due to this years after they got the car with many more miles on it. Best of luck.
I've posted this also on the Pete's board. On the Boxster racing board there was an interesting discussion about the amount of (or lack of) negative camber available in the 986 stock suspension, which hampered it's handling capabilities. Does anyone know if the 987 has the benefit of more available negative camber and/or is the PASM option would by itself allow for more negative camber due to it's lowered suspension? Thanks fo rany help. Mike
csory: Congrats on the new car. I'm sure you'll have great fun with it. :thumbup: As a former Miata owner, I'd be curious about your comparisons of the two cars. Ours arrived Saturday (ordered 9/2, built 10/13) but wouldn't be prepped until 11/14. We're going to pick it up this Saturday; my wife thinks the car isn't going to be delivered until xmas week and we' re going to the dealership under the excuse of looking at the new Cayman they just got in. Can't wait to see her expression.
I had the Kumho MX's on our '99' and they for the most part they were OK; priced right and I'd expect you'd probably get 20k from a set. The down side , IMHO, was a less responsive tire--slower turn in than the michelin MXX3's that were OE on the car and noisey after 6 or 7 K . A much softer ride than the MXX3's due to what I thought was a softer sidewall. My biggest gripe was noise, between 30-60 mph-- they sounded like truck tires. Good grip and they do communicate when they start to loose it A decent tire on an auto-x course and at a track this summer the tire had adequete grip and was easy to manage on the track. For a cheap tire to run DE's or auto-x on a spare set of rims these aren't bad tires. My experience driving when the tires were new in cloud burst was they weren't terrible for terrific--somewhere in the middle. For everyday use there are better tires out there; I'd spend the money and get the PS2's.One other thing-- People in our club running the Goodyear F1G3 (?) like them a lot--just don't track them.
For track tires, I'm thinking of going the other way with our incoming 987. Using the offset calculator that is avaialble on a website, by changing from the Boxster S 18" wheel and going with a set of Boxster style 17" wheels there are no clearance issues but the fronts come in 11mm and the rears come in 13mm. BTW, I'm considering 17" wheels since I already have a set and 17" tires are significantly less expensive. My question is, does reducing the track by these amounts make that much of a difference in handling that spacers would be required? I'm not terribly concerned with the asthetics seince these would be track tires. If spacers are required, are what kind of pricing are we talking about for a 10-15mm spacer? thanks for any help.
The 615's are not anywhere close to being an "R" rated tire. With 2 drivers at an autocross, they easily overheat - not quite as easily as the older Azenis 215, but still way more easily than a Victoracer. They also simply do not have the grip of even a Yokohama A032R (and that's saying something). As street tires go, they have exceptional grip and do seem to work way better in wet conditions that a Bridgestone S03 or BFGoodrich TA. However they are still street tires. Graeme All right, then, if you were looking for a tire to do double duty--auto-x & DE events in a 987 Boxster, which would it be.? I like the Victoracers but the sizes don't work for the new car. I also need something I can drive 100 miles to an event and not be too concerned about getting caught in a shower The SSR seems to be gone; any other similar choices or would a good max performance tire do the trick? Thanks for any help.
