OP just keep the S1 Honda. A Cayman is never going to be anything like a Lotus. If you have a good Honda S1 you'll regret letting it go for something a lot heavier.

I have a Cayman S daily complete with LSD and PCCBs but it will never go near a track as I have a couple of Lotus cars that are just better suited to the task. With no effort at all you could have a 700kg 350BHP S1 Honda that would destroy just about any Porsche on track. Even an NA S2 Honda is quicker than a Cayman S or R.

The Cayman is a truly brilliant all rounder but anyone using one on track that hasnt had a Lotus or similar car should really try it. Best case scenario you are hauling 400kgs round that you simply dont need.

Upcoming ring trip.... The Cayman is going because its much better suited to a long road drive and quick scoot up a little private road.

Congratulations. They really are great cars. I have run my standard Cayman R in a road class at a sprint and it beat two GT3's to win its class.

Not entirely relevant - but some useful info here http://www.caranddriver.com/flipbook/porsche-911-g...

If you go through the pics it gives the weight savings of removing/changing various bits on a GT3/RS, some of which might apply to Caymans too.

Composite doors dropped significant amount of weight. Car is at about 1175 kg now. Plans to go to about 1050 kg.

1175kg is an extremely impressive weight. Well done!

It does give you an idea how much air cons weigh, how much the infotainments weigh and what a waste of time the silly door pulls are.

How much does paint weigh?

Remember Mercedes' silver arrows?

A lot less dry than wet. Most of it evaporates.

That is one crazy 986 but fair play to you for doing it. What was the spec of that?

It was fairly tame on power. Base 1999 Boxster, 2.5 liter with larger throttle body and headers, 6 speed S transmission, all GT3 suspension and KW coilovers. New owner has put a built 2.7 that makes about 250 HP in the car. Its a national level autocross/Slalom car in US now.

Nice. It sounds ripe for a lower final drive too.

Short 23 inch race slicks helped with that!

I have aluminium doors, and made 1.00mm thick door cards and then had them flocked. Inner door handles off a 1980's VW Bus!!!

The car is away at the race shop as I am not racing it for a month. When it gets back I'll take some photos of the interior.
Sorry, been very busy and forgot about your request!

Thanks! Those look great! I went to composite doors so bypassing RS style door panels now.

I'm to 1135 KG now. I still have full dash, AC , Heat, Stereo, carpets, even have cup holders. I'm going to try to hit 1000 kg. That should give lotus guys fits.

Pretty impressive - but does show however what an achievement the Alpine A110 is to be even a bit lighter fully fueled.

If I go to smaller wheels and tires than 18x11 with 335/30/18 DOT R in favor of 16x10 with slicks and go for CF roof, fenders and rear quarters I'd get this car to 1000 kg no problem. For steel chassis car the cayman is very efficient once you get all crap off the car

With 350 HP 3.4 liter 6 cylinder my car is becoming very quick!
