Another RSR Clone Project

[phe]

Forget, but I have and I "vote" for the LSD.

This is a way to survive to the power.

If you use to drive a stock SC or Carrera 3.0, you will feel a HUGE difference.

This is not the same story to keep control of this kind of settings. I mean the limits of the car are higher, so the consequences of errors are also higher...

sounds like a great setup to me Tom. Id leave the fancy diff and final suspension spec to after youve run it in and got some shakedown miles on the car, that way youve got some idea of how it drives before you start fiddling. on the tyre issue, Michelin have just started re making the classic TB15 series tyre in the correct spec size for the 2.8 and 3 litre RSR's. Im building a 73 RSR replica myself and was having BIG probs getting tyres, until these babys turned up. I ended up buying a pair of 290/40/15's. Ill post a pic of them tomorrow.

Below is a list of the current TB series tyre sizes available.

1903 mm
11 to 13 inches

they are all in a REALLY soft compound but michelin will release them in other compounds if they sell well enough. Mind you they wern't cheap, my pair cost me £520 or in your money $930 a pair! Id go with the fifteens any day over the larger wheels. dont get me wrong, the big wheels look good, but for that bad-boy old school look the 15's win hands down.

Andy, I agree that the 15's look best on the early cars. If you're building a correct-looking RS, they're the only way to go.

But if his goal is to develop the thing as a track car, he's going to be hobbling himself with the tires available in that size.

[geof33]

I have to say, Jack has me convinced of doing the 17" route through Lindsey.

The 15's look awesome, but there will be a day, sooner than later, that the tires will no longer be available, and for the serious $$$ the 15's cost it's not worth the problems. I'm building my car for both street and track (mostly track) and want to be able to choose whatever tire I want in the coming years. I don't want to be stuck with a sweet looking set of wheels I can't use.

The big question is how long will Michelin be making these tires? What are they going to consider "good sales" There can't be THAT many 11X15 wheels out there these days. I'm sure there are a few, but not a huge amount...

The other bonus of the 17's in they will run about 1/2 of what a good set of 15's would run. That pays for ALL of my fiberglass!!

[adomakin]

Jack+Geoff, I hear ya. They are a very dear and increasingly more awkward to use. Im still gonna post the pic of my tyres though, you gotta see em!

I thought some of you guys might be interested in some photos of my RSR clone project. The first is a before photo taken last October before I started the project


The sconod photo shows the car mostly stripped with the rear flares fitted as a templates. I used the templates to mark the body work before cutting back the quarter panels to facilitate stripping the undercoating from the rear wheel wells.



The third photo shows the R/F whelel well after stripping and priming.



What do you guys think??

[adomakin]

i think that i wish i had them metal rear arches! Ive got an oak tree in my pants

[Jack Olsen]

What's the story on the rear flare pieces?

[tom1394racing]

Jack

The rear flares are fiberglass from the guy who is doing the body work.
Thye're custom RSR flares like the ones he used on his Parade winning 912 RSR project/race car. I used them as templates to mark the rear quarters and then used a sheet metal nibbler to trim back the bodywork.

[Jack Olsen]

Ah. On the left side, especially, they're reflecting in a way that made them look like steel.

Cool project!

[bigrubberjeep]

How much wider are the flares on a RSR vs. a Turbo (with)?

Or does it just look wider to me?

[Jack Olsen]

Just looks wider. They're basically the same, with the exception of the 3.0 RSR, which got another few inches.

[bigrubberjeep]

Hey Jack - Let me ask you a question, since I concider your advice as good as any.

If you had my car
85 Black with tan Turbo look
Crome Fusch wheels with new Yoko AVS Tires
Stock motor (added K&N replacemtn filter but have stock filter still in garage)
Cat bypass
Magnaflow Muffler (single in/out)
Strut tower brace

What would you do with it if you were in my shoes?
I feel like doing some kind of conversion to it but at the same time I feel like it's as good as it can be without spending mass money for a higher displacement motor.

In other words, if you had the car in your garage tomorrow, what would you do with it?

[Jack Olsen]

Personally, I would take it out on a few track days -- start to learn what it's capable of.

I wouldn't change anything about it, at least initially. The Turbo-look is a gorgeous car, and the 3.2 is a pretty capable motor. If you found you liked tracking it, and wanted to improve its capabilities, you could beef up the suspension. But I'd wait at least a year before you did any of that.

[phe]

Oh yes turbolook is cool.

Just had a track day at DIJON-PRENOIS (France) last sunday this is an old F1 track. Fast and fun.

They took the coolest picture of my car.



First track day without any problem since a long time. Real dream.

OK you dont beat 993 RSR, GT3, RS cup.
Ok I have a huge work to improve my driver capabilities,
But you have many friends to play with SC, 3.2, 964, 964RS, Carrera 2.7,...



Do not worry, 3.2 is great fun even on fast track.

[bigrubberjeep]

Thanks for the info Jack

[geof33]

Bigrubber... you got it bad don't you???

So, you recently purchased your car, cool. Did all the "bolt on mods" and yet heven't spent the time to learn to REALLY drive it... (or have you... you have made no comment on PCA stuff or track events.)

I agree with Jack, get it on the track and learn just what that car can do... IT WILL SCARE YOU, if you really get in it. Don't try to change what is already a really good car. Drive it to death first get used to it, and have some big fun. Then get a track car. It has taken me 7 years behind the wheel of my "stock" 3.2... I don't want to hammer my nice "driver" anymore. So, the track car it is for some real fun with a little less "worry".

[bigrubberjeep]

geof - you are on the money when you say I got it bad.

I do want to drive my car at a track event or something. I want to smell the gas and tires burning on the track (well maybe not the gas)

I guess I just feel that my car is very mild - but then again,what do I know. I feel exacly what you mean when you say to later on buy a "track" car so I am not so concerned with ruining my daily driver. I guess I just have to make the move and actually get out on the track.

Here is one more question. can a 5 point harness be installed without the roll cage or brace?

If so then I will get a 5 point harness and look for some events this month. I was thinkingof doing the Open track event on the 19th at Willow Spings, do you think this is a good event for the rookie?

You need to get into the local PCA and do some DE's first. I'm not sure if you can just enter an open track event like that with no track experience. I wouldn't recommend it. Besides, you have no idea what to expect in that car at the limit. That's why you need to go get some DE time. It can be invaluable because you get to learn in your car. All you need are a helmet and some gloves. A five point is not nec at this point either. And yes, you need a harness bar. Go get in that seat time and then see if you think your car is tame. These cars aren't straight line dirvers. What makes them great is how fast and deep you can go into corners, the feel of the rear end hooking up in throttle steer, and what happens when your on the line in a corner and lift the gas...

PS start a new thread... so this post isn't completely hi-jacked...
