this sunday i went down to englishtown for the nhra supernationals, and of course there was a great turnout of venders. i looked at this booth with rear ends and driveshafts, the guy there was friendly and put his fan on my g/f since it was so hot, and we started talking....

i told him about some guy doing a REAR END SWAP FROM A VETTE INTO the s2k, he showed me his driveshafts, carbon fiber weighs 4 lbs. and is tested to 1750 hp. the cost is about $500, he told me to keep in touch(his shop is in colorado) and he wants me to send him the measurements to make sure they can make a shaft for the s2k..

now, does anybody here know what the measurements are on the s2k driveshaft so i dont have to rip mine out in the middle of the work week?

also, i stopped over at the simpson booth, and i asked about the proper way to install the harness, and i was confirmed by their rep and the instruction manuel that the belt must be installed at a 90 degree angle from the anchor otherwise its just going to bend the floor...now there was a install post on here where i mentioned this and someone told me they were installing 100's of kits and that wasnt true, the rep told me thats scary but shes seen plenty of cars at the track installed incorrectly and the safety check shouldnt allow u to race like that, but for some reasonit slips by. but in case u guys want to stay safe, keep that in mind.

i apologize for the length but any measurements out there?

 

Wow...someone's using a Chevy rear end for the S2K. I'd much rather go with a Ford rear end, there are a lot more, cheaper final drive ratio options made for the Ford rears.

IMHO, going lightweight drive shaft isn't worth the cost for a street car and what you'll get out of buying/using one (unless you more highly value the CF 'bling' piece on somthing that is quite rare for the S2000 market).

Complete and ultimate racer's may find a lightweight CF mainshaft useful. There's a long winded speculation and explanation behind this, but I'd rather not type it out.....read about it over at S2Ki.

 

AJ-R's time attack/street car runs a custom carbon drive shaft cuz they're cool like that.

Anyway, since Luder was a complete *** and didn't help you out, (j/k, Urmil), I will try. We have an S2000 in our shop right now that has the drive shaft out. I won't be there this week, but you can call them and I'm sure someone can measure it for you.

Isn't $500 insanely cheap? . . . any chance of a GB on this in the future?

 

Thats the beauty of buying parts in the US, and parts that there are plenty of.

 

the driveshaft and the yokes together would be about $700, they had the booth set up, i held the driveshaft in my hands, its only four pounds and there is a cheaper metal versian that is 8lbs, but since the s2000 loses 30 hp to the read end and shaft, this would help free up a lot of that, to me $500 is worth the gain on top of everything else that can be done...thanks for the help tho...but what is the number? u never left it?

and the reason for using the vette rear end was because of fitment and capable of higher performance, less restriction, this s2k is the speed record holder for s2k's at the salt flats.

thats pocket change

 

lol exactly, yikes = wow how cheap

 

wow well the cf shaft i looked at was 580 plus 180 for the yokes, but i dont know if i trust cf in a daily driver, so im undecided...i wonder why that shaft is so drastically different in price, im gonna email the rep and see what the deal is, ill let him know theres some honda-tech interest and see what i can weasel out of them

 

I doubt that you really got the correct $ on the Cf shaft. CF shafts are very expensive and would also be a difficult fit into an s2000 due to the cv joints.

At $4975.00 if you ad a little bit more I will supply you with a new 8.75 rear w/33 spline axles true trac your choice of ratio a new u joint style driveshaft with adapter plates and level 5 Drive Shaft Shop Half shaft kit

the price for the kit to convert the rear end sounds right.


The price for the c/f drive shaft sounds right, too. The only ones available for the S2000 right now are made in Japan and they can charge whatever they want. A c/f driveshaft for a domestic vehicle can be had cheaply.

I know AJ-R had a custom carbon shaft made for their dual duty street/time attack car. Maybe contact them if you're looking for just a c/f shaft.

 

well here is the response to the email i sent the rep...

We have done that shaft once before and the cost is so high because
we
have to do a custom trans yoke, rear end yoke and cv's. You are looking
at a
$3000.00 drive shaft with everything. If your intrested please talk
with
Bret and he will have all the questions you will need to answer.

he is referrring to the aluminum shaft

 

yeah 500 is super cheap...

 

Thats some BS. I can have CF shaft made for $800 or so. And yes, the driveshaft are used in NOPI race cars

 

so whats the story on these corvette rear ends? there are mny types of corvettes. which year are you referring to?

 

Jtuner magazine from the UK recently published an article regarding the using of Carbon Driveshafts,

They stated many times that the strength is superior to the metal versions, and the weight savings considerable.

You might want to check their website for the article; it was very informative.

 

yes carbon has a lot of advantages, unless its a street car and u run something over that slams it and breaks it in half

 

anyone have any pictures of one?

And how do you balance a CF driveshaft?

 

funny nobody has mentioned balancing of these aftermarket unit. the tolerances have to be dead on , on all moving, rotating parts.

 

um, post above yours
