Attention GT4 owners, your input needed - Page 1 - Boxster/Cayman - PistonHeads UK

This is an issue I have with my Porsche 718 GT4 but may also be applicable to the 981 GT4 as well. It is to do with the paintwork on the rear wing (spoiler). I noticed, when cleaning the car, there were slight indentations in the top surface of the wing. These occurred above where the bolts secure the wing to the uprights. You have to catch it at the right angle and light but where the bolt comes up from underneath there is one of these ‘dimples’ in the wing top surface. Its as though the bolts have been overtightened but they've been checked and are at the correct torque setting. My car is a 21 plate and has done 12k miles. I’ve had the car from new and there has been no damage or work done in that area of the car. I would be obliged if GT4 owners out there could check their cars and report back as the Porsche centre have said they’ve never seen it before. At a regional Porsche Club meet, I saw another 718 GT4 that had the same issue. I would be interested in your feedback. TIA Chris Edited by chris.t on Wednesday 9th April 11:16

There was a thread on this a while ago - and I also did have it on my 718 GT4.

Known issue. Related to the bolts. I say issue - think it's there from when the car rolls out the production line

Hi Chris, I too noticed this a while back and my thread is here - https://www.pistonheads.com/gassing/topic.asp?h=0&... In short, they are all like that. It looks like it’s to do with the bolts being over torqued but I was in the Porsche approved body shop and they had one off a car they were respraying. They showed that the dents wouldn’t be caused by torquing the bolts.

In fact if a car doesn't show this shrinkage it may have had paint ???

From memory my 2015 981 Gt4 didn't have this issue

Just to add I'm currently going through a warranty claim about this. I have gone through the paperwork and can't see how it's not covered. In the agreement it states that any 'optical' items are not covered. I took that to mean lights/glass/bulbs, that sort of stuff. However Porsche actually mean that anything that can be seen is not covered Anyway that was their initial response. They have obviously realised how ludicrous that sounds and changed their reason to, "excessive load has been applied to the wing", which it hasn't, I've never gone fast enough and I haven't let any 'large' people sit on it. To be absolutely honest if it doesn't get any worse, I'll live with it, but what if it does? What if it starts to become a structural issue such that the wing would part company with the car at high speed? I need to cover myself for this. Look, I know a catastropic failure is unlikely but I'm no expert on these things and I don't want to be responsible for decapitating an unsuspecting motor cyclist or the like. Oh by the way, my bad, I did post a few months ago about this in a separate thread, bit of a senior moment starting a new one!

I think most of them are like that albeit some are a bit more obvious than others. With that in mind, a replacement is also likely to be the same. The wing is attached via an internal bracket and so there’s no reduced stability or anything as a result of these.

Slight overreaction there 😅 the wing is clearly not held to the car by its top surface... the fixings are internal.
