I'd agree with Cmoose in as much as a standard Gen 2 987 3.4S is similar to a Spyder and the dynamics could be replicated for a lot less than the cost of a Spyder.
I sort of agreed, but not a leggy 15k beater and £5k as he stated , that was just comical.ATM said:
To some people a 15k boxster is not a beater. If thats all the budget you can muster then the entry point to a gen 2 987 S will be 15k-ish. Then I think Moo is suggesting that for 5k you could add spyder spec dampers, springs, some lighter seats and a lighter battery and that this combo would get you close to the spyder in terms of weight and CoG and that you would be hard pushed to tell the difference from a driving dynamics perspective. He is not suggesting the car would be quicker round a track than a modified spyder like yours.
light weigh wheels, tyres, brakes, Spyder dampers, ARB, bucket seats, Battery, Geo and labour for £5k where do I shop ?And still 80KG more mass and a higher C of G.
I agree you can make a nice car from a base car but the BIG trick items on my car are the PCCB's, the lack of weight and the low CofG, ALL STANDARD
forget the body work and the extra work I have done with GT3 parts etc £5k on a base 15k car will not get close to why the spyder is special to drive.
£10k maybe and then £30k to match my car. The devil is in the detail as always.

I was thinking that, but actually that would likely just point out that 19" wheels have more grip that 17" ones.
How does that work then?Unless the 19" tyres are considerably wider I dont see how they would have more grip than 17" tyres?
If they are all the same width the grip should be the same surely?, I thought the only reason for bigger wheels is to enable fitting of bigger brakes.
If bigger diameter wheels means better grip then why are F1 cars still running 13" wheels?

I am always surprised how few modified Boxsters and Caymans you see for sale. I would have thought they make a great starting point for these sorts of mods but I almost never see them, which as a potential buyer is a great shame (clearly not a £5k project for the original owner).

If two wheels have the same width and the same external diameter then they’ll have the same grip as one another- but if two wheels have the same width but one has a greater external diameter then that wheel will have more grip due to the longer contact patch.

F1 cars have very wide sidewalls, the full diameter of the wheel is not that of a 13” Mini wheel.

But on a 987 the external diameter of the tyre is largely the same due to the different tyre profiles.F1 cars have very wide sidewalls, the full diameter of the wheel is not that of a 13” Mini wheel.

I question this myself, when you do see a modified example more often than not it's done for visuals and not performance. Things like Pandem kitted Caymans running air suspension. I guess a major reason it's not common is lots of people seem to consider a Boxster/Cayman as stepping stone to owning a 911. The other thing is they aren't easy or cheap to get power increases from and power potential is what ultimately decides how popular a car becomes as a tuning platform.
If I had a 15k Cayman and 5k, I could make it 450bhp

Wow thread seems to have gone off at a tangent. Just back in from a 3200km round trip to collect the new toy, a bit mental to say the least 
Spill the beans please, looks very intriguing!I've reveal the details tomorrow, too much to list, it is just weapons grade loony
You want detail; well due to the depth and attention to detail with this car I’m just going to lightly skim over some of the design and construction pics, I would literally be here forever for the full breakdown. It basically makes the £230,000 Alfaholics GTA-R look a bit tame. The car was built by a fellow aircraft engineer so the technology found on this car is more akin to what you would find on an aircraft (MIL spec loom, L163, Titanium…). It truly is well beyond of scope of normal automotive tech. The car started life as a 1975 JT Junior 1600. The builder had the car 13 years. He started with a completely restored shell with all the other components in boxes. The early idea was to use the Alfa engine but this was ditched fairly early on. In search for a new powerhouse the F20C was chosen. Those who know a thing or two about NA engines will most probably know Honda's F20C engine held the record for producing the highest specific power output for any mass production naturally aspirated piston engine, at 123.5 HP/L, until Ferrari began production of the 458 Italia in 2010, which produced 124.5 HP/L. The F20C revs to 9000rpm, is unbelievably strong and reliable even at this level of tune. The engine was completely stripped down and rebuilt as new then some special track orientated modifications added, baffled sump etc. A completely unique custom fabricated ITB system was made, not only that it uses Formula1 engine type injection with the injectors housed within the trumpets; a true work of art as you’ll see from the pictures below. It is now mapped and running on E85 so it is a very green machine. In the current state of tune it is making around 255bhp and weighs just under 900kg. Some of the detail and lengths gone to really are astonishing, 180mm wider track for instance… It really is a one-off in the truest sense.
The car has been through various stages of design and some aspects of the early work presented here may no longer be on the car. The pictures are roughly in time order. The final car is fully FIA compliant and certified so can be used in most race series. It has also been road registered which is some achievement. My aim is to dial it back a little and attempt to make it TUV compliant for registering in Germany and just simple marvel at the quality of workmanship and engineering.
Apologies in advance if you stumbled across this thread looking for deviated stitching
This is only a short summary but I’m sure that’s enough of my blabbering, I’ll let some pictures do the talking. Let the engineering porn commence!!!
