I went back to 235 front (swapped to Yoko AD08R all round) giving much more balanced stagger imo... That's weird as some people run 265 front with 295 rear, yet haven't heard reports of floaty front ends..... Link to comment Share on other sites More sharing options...

pstarkey Posted January 26, 2019 Share Posted January 26, 2019 Great thread I am doing some similar mods to a 2006 Cayman S I purchased a few weeks ago. With the steering wheel when you fitted that did you code out the airbag lights or fit/solder in resisters to the two airbag connectors?

jcm987 Posted January 27, 2019 Author Share Posted January 27, 2019 @pstarkey Thanks. Yes I have resisters that stops the airbag lights from coming on. If you get the bos kit that fits lots of VW group cars it has the connectors inside and its a simple solder. It only took around 20 minutes to do.

Popular Post jcm987 Posted February 25, 2019 Author Popular Post Share Posted February 25, 2019 Wing on. Finally got to take the Cayman out of hibernation for a sunny drive. One thing I've learned when arriving at a quiet old village pub in a big winged, stripey, loud and obnoxious track car is - old people hate you 2 3 Link to comment Share on other sites More sharing options...

jcm987 Posted March 1, 2019 Author Share Posted March 1, 2019 Cayman just received fresh suspension geometry set up from Parr and feels amazing, even more aggressive with the camber. But had to cancel track day plans due to a cracked exhaust manifold and broken cats, with completely eroded bolts replacing them is going to be a mission. Has anyone changed their headers and found issues with the bolts? Link to comment Share on other sites More sharing options...

I've had several things done there on my S1. I've heard (on other forums) that removing the manifolds can be a pig due to corroded bolts... IIRC I believe oxy acetylene &/or a specialised drill Jig is required as the header bolts almost always shear below the block face!! Link to comment Share on other sites More sharing options...

The man in the know is Gert Carnewal, he has to deal with this all the time and will no doubt know the best way of tackling seized bolts. Either that or drive to Belgium and get him to sort it (along with his sport headers) Link to comment Share on other sites More sharing options...
Popular Post jcm987 Posted March 26, 2019 Author Popular Post Share Posted March 26, 2019 We added a lightweight Odyssey battery last weekend, saving around 11kg! Quite a big weight saving given the battery is mounted up high. New policy: every time I add weight (wings, cage etc...) I must save some weight. 4 Link to comment Share on other sites More sharing options...
crafty1 Posted March 27, 2019 Share Posted March 27, 2019 Nice weight saving, I am thinking about doing the same soon. Which battery and bracket did you go for please ? Link to comment Share on other sites More sharing options...
Mavrik Posted March 27, 2019 Share Posted March 27, 2019 (edited) @jcm987 What model Odyssey have you fitted? PC680 maybe??? I have a Lithium LiFePO4 in my track bike & had one in my Fireblade engined MK Indy kit car... The weight saving is crazy!

Dougle_turbo Posted March 27, 2019 Share Posted March 27, 2019 That’s an easy win on weight reduction, nice work. Where did you get it from and what was the damage? Link to comment Share on other sites More sharing options...

Porsched eggs Posted March 27, 2019 Share Posted March 27, 2019 (edited) I know a few users of Odyssey batteries in the Lotus /vx220 community but the idea is normally better than reality. My mates Elise has one which works well but he uses a battery cut off switch because it stopped holding the charge to start after the first winter. Ive spend lots of time and money on track upgrades on my VX, and the wheels is a good start, and if you can get ceramics they would be a great combo. Unsprung weight savings are more important. Seats is also an easy one. i have Tillett B5s in my car which would save a guesstimate of 25kg per seat in a 987 depending if they are full electric and heated etc. Then gut it!

Porsched eggs Posted March 27, 2019 Share Posted March 27, 2019 (edited) If I were building a Cayman track car for semi sensible money I think I would go: forged wheels ceramic brakes seats plastic rear and side windows sump baffle delete the rear wiper, AC compressor, blower unit if you have a heated screen, audio, soundproofing, airbags, carpets, headliner, wires (it's amazing how much wiring weighs), rear washer, all adaptive systems (lights, shocks etc), spoiler motor, wing mirrors, all plastic trim, centre console tunnel, cental locking module and abs module (and I'm sure there are others) id strip the inside of the doors but leave the inner ones so you can get an mot and down slice your arms getting in! Might need something to code out all the errors from the missing systems, but apart from the wheels, brakes, seats and windows it's free, and you might make a bit back on the parts you scavenge. But you'd struggle to sell it on... lol. Edited March 27, 2019 by Porsched eggs 1 Link to comment Share on other sites More sharing options...
Porsched eggs Posted March 27, 2019 Share Posted March 27, 2019 My friends and I are in the middle of this build, it's a 180bhp Leon Cupra. Even without swapping to lighter parts the car can hold station with a Golf R. Link to comment Share on other sites More sharing options...

Yep done most of that already, full list of weight saving stuff: Carbon GT3rs seats (8 kg) each big weight saving here Odyssey battery (11kg) Team dynamic track wheels, although they're actually heavier than stock Porsche KW suspension saved around (>4 kg) per corner Plastic race windows will be ordered if the battery can't consistently do the electric doors Deleted / completely removed rear wiper motor (5 kg) Deleted wing motor (5 kg) All front and rear boot trim/carpet removed (>10 kg) Rear speakers removed Link to comment Share on other sites More sharing options...
Porsched eggs Posted March 28, 2019 Share Posted March 28, 2019 Good effort. if you want truly light seats try Tillett, they are 4.2kg each,and I've driven the car to Germany in one day with no back ache. Reverie are sub 3kg but I found them agony when I tried them. OZ alleggerita hlt would be a good option in 18", circa £1600 plus tyres. i think beyond that you will need to look at replacing panels for lighter.

My pockets were never deep enough so standard GRP was good enough for me lol Link to comment Share on other sites More sharing options...
