18inch or 19inch wheels on a Boxster S 987? What about tuning it?

I am going to buy a Boxster S 987 and I am in conflict in myself whether I should leave the standard 18inch wheels or fit the Carrera S rad - which is extrtemely beautiful for me-. I am not sure whether the 19inch wheels will slow the car down. Has anybody driven a boxster S with both 18inch wheels and 19inch wheels? Is there any difference?

I am planning to tune a bit too, speedart has a completed package which bossts the performmance another 35hp. Has anybody fitted something different? the cost for this is 3780euro + ecu reprogramming - I don know the particular cost-.

If somebody knows better can you please enlighten me which companies tune the boxster s 987? In the internet I have found very few companies that have done anything similar - they only manufacture exhausts- and only ruf goes hard on tuning it but they fit the 3.8l engine and they ask 40000euro for it!

I look forward to anybody's reply, Thanks in advance

M-porsche. I don't think 19 inch wheels will "slow the car down" as you say, vs. the 18 inch wheels. There may be handling differences and ride comfort considerations to evaluate. How are your roads in your area?

I selected my 987S wheels purely on aesthetics. Maybe someday, I'll be a good enough driver that an 18 or 19 inch wheel can truly make a significance difference in my driving performance.

This was my choice- The 19" Carrera Classics:

I have 19" Carrera S on my 987 - cosmetically it looks fantastic - handling is awesome, ride is good, noise is minimal. The car still goes fast, baby!!!!

People say that the 19" wheels will be a rougher ride, and I think at least one reviewer recommended PASM with them. Porsche's factory driver (Rohrl or whatever his name is) also says he prefers the 18" wheels for handling reasons.

But I'd go with the 19's. Get the Carrera Sports!!!

I live in Greece and the roads are not so good...but I do love the 19' wheels Carrera S rad looks'.I have driven a boxster s 987 manual with 18inch wheels and a boxster s 987 tiptronic with 19inch wheels and the tiptronic car was much slower then the manual one. That is why I was wondering whether the wheels had their effect on this too.

What about tuning it? Has anybody in this forum done anything similar? My aim is to get it to reliable 320ps. I ve never found though any company offering such a package except speedart who says they boost it with 35hp extra hp with only intake, exhaust and ecu. Has anybody tried that? In the previous boxster s (986)what was the maximum reliable horsepower that somebody could have?

if you look at the 0-60 ratings for the manual gearbox vs the tiptronic it can be almost up to 1 or more seconds different - thus the feeling of being slower in the tiptronic is more related to the transmission and not necessarily the tires.

I am buying a take off set of brand new CaymanS 18" wheels/tires (for track wheels) so I'll be able to compare them back to back with my CarreraS 19" wheels within the next few weeks. I'll post my impressions.

You are right about the 0-60 times. The manual one gave me the impression it had 30hp more.

Carl AMG you will answer our question once and for all.



Does anybody have the article from the excellence magazine about the sportec porsche boxster 987 with the 3.8litre motor on? What were the reporters' impression about it?

CarlAMG...great move! I think the 18" CaymanS wheel looks very nice.
Please post some pictures when you have'em on your Boxster.

I have the 19ís and think they look better on this car than just about any wheel on any car around. The handling with PSM off is incredible and very predictable. Having said that and driven a new S with the 18ís I will say that on bumpy uneven roads the ride does suffer significantly. You will feel every minor difference in the road and if that bothers you I would think twice.

I would get the 19ís again in a second but my other car is a pickup (I do live in Dallas) so ride comfort is not big priority for me.

I'm also looking for wheels and need to make a decision between 18 inch and 19 inch wheels...

Any other information regarding the ride comfort or personal experiences would be appreciated. Has anyone installed 19 inch wheels here and regretted it? I also hear that 19 inch tires cost much more and have less options for that size for available manufacturers. Any information please?! Thanks.

I test drove several 987's with the 18's and when I test drove one with 19's, the one I ended up buying, I didn't really notice any difference. The 19's ride is not harsh. From what I've seen, the 19" tires do cost a lot more, but I absolutely LOVE the look of the 19" Carrera Classic wheels. They really fill up the bigger wheel wells of the 987's. Where are you located? Maybe someone is near you who has 19's and you could go for a ride to see how they feel.
