The Track Cat...

kinda cool. i dunno exactly how it would work but i would be down to bolt it up for shits if i wasnt a coupe.

this makes no sense!!!! how wide a tire is, has no effect on gearing!

[ThatGuy]

I believe he's referring to to the torque required to move such a large contact patch. Which a different gearing might be better suited to, given the minimal torque provided by an average KA engine.

I believe DEF is referring to your typical 275/40-17...like someone has already mentioned, above.

And a 275/40-17 is a LARGE diameter tire, screwing up the gearing.

(And before someone points out that is "could be" a 275/35-16...275/40-17 is BY FAR the most common 275-width tire out there...so it follows that he was referring to a 275/40-17, especially on an S-chassis car).

orion got it right. I was obviously still talking about the 275/40-17's that were the subject of the conversation at that point. It's a TALL tire, which reduces your drivewheel torque and lengthens your effective gearing.

Stop shooting down shit you don't understand.

i'm sorry if i seem retarded here, but i completely fail to see where an s13 is even remotely close to an F1 car...

Oh well, glad to see at least a few people realizing this is a pretty ridiculous "mod" that doesn't look like it has much thought or engineering put into the finer points.

Thats ok i dont have a KA nor an SR, and i've got a 3.54 diff.

even if this version isn't practical, maybe v2 or v3 will be an improvement....

I'm with you on this one. I have an S14 and never plan to own a hatch but it is sort of exciting to see new inventive products out there. If anyone has the means to test this equipment, please lend your experiences.

BTW, I wonder what it would do for wheel clearance? Of course there must be some sort of linkage to the spindle...

Its getting there, not done yet, just figured this track cat thing would perform similarly to a quality set of coilovers and give me some extra rear tire room, but then I saw it wont clear the little privacy cover

[Def]

I like how keeping the privacy cover is the most important thing... hah

If you really want a wide tire, get one that wasn't designed for sports cars back in the mid 80's. Go with at least a 285/30-18 if not wider.

18's usually look a bit silly on an S13,not to mention an 18" drag radial usually runs about $100 a tire more than comparable 17" size, and im quite sure the ones I want to run arent even available in 18" but dont feel like double checking right now.

Yes keeping the privacy cover is an important issue for me, hides the stereo, reducing the likelyhood of problems, also hides the nitrous bottle and shields it from the sun.

[s13 @ fullboost]

I do not understand it fully but it does look like a cool set-up that being said I would like to see more of it and learn more about the system the website is very brief

[dynamicck]

The idea is great. the design is can be improved.
Why isn't the bar straight vs being bent? (the bar/brace that connects both shock towers.)

When the Bar is bent, all the force is being pushed downward on that bar. That single bar is holding the entire weight of the rear? Does it flex under extreme load?
If the bar was straight the lateral movements would probably not require extra bracing/reinforcement.

[stinky_180]

that setup almost looks like my mountain bike full suspension set up (maestro suspension technology) but the pivot looks like its going to destroy the upper shock mount under rebound. very interesting, never seen this on an s13 before.

[let5l1de]

I used the cantilevered coilover setup on the rear of my Class 8 F-150 my cousin and I used to run in the MDR circuit. It's a good setup but must be well designed from geometry, springs rates, travel/stroke, compression, rebound and preload among other things, for each and every application.

^ pics or it didn't happen!

[simmode1]

LOL... we talked the Track Cat suspension system to death about a year ago on NICO... While it is interesting, it's benefits don't seem to greatly outweigh the uses of a decent coilover like most of us are used to.

Plus, when you tally up the price for a Track Cat system, you could buy a high dollar coilover system for around the same amount. I mean, it's like $900 just for the rear setup. You still have to spend more money on your front coilovers and dampers to use on the rears. You're gonna be spending almost $2000 or so...

Not saying it's a bad idea, but it's overkill for most of us, IMO.

[Def]

I'm sure the intellectual giants on NICO came up with all sorts of insightful technical analysis too...

[S14DB]

So, wait. It's $900 without the motorcycle shocks?

Yeah... the analysis is about the same as you're seeing in this thread. Except that it was a year ago.

It seems that way, but it's hard to tell since the seller never responded to any of our inquiries...

[ruleofthez]

Did anyone check out the other stuff on their site though? They have some pretty good looking headers on there and some others parts although not many.

[s30datsunl24]

It does make adjusting your suspension a breeze though...as long as you can figure out what you're doing

[BoostSlideWayz]

I wanna get this it just seems like an awesome idea. I love how its bolt on from what it looks .... and imo there is no down side to this on any type of driving..

You do that buddy. Sounds like you've got it all science'd...





NO DOWN SIDES...





EXCEPT BEING STUPID AND POORLY DESIGNED.


BTW - nice way to bump a dead thread.

Honestly I would have to agree....

Probably lose more in the added weight haha

[Datenshi]

You guys are crazy. Look at the pictures again and realize what kind of car this is in.

It's the furthest from a "Race Car" I've ever seen. Completely stock interior ( Why is the interior in there in the first place?), stock seats.. full sound system all panels and carpet.

While it would have function for a F1 car I would assume (Not knowing much about this at all) I hardly think this guy is the fucking track warrior of the year.

If I installed a 3" HKS Hi-Powered Exhaust, 305 width tires, massive rims, a couple defi gauges and a body kit SLAMMED on some cut springs a huge carbon fibre GT wing and canards with a stock car.. sure.. I look like a pro-star, doesn't mean the car does shit. Oh, and don't forget the stickers hahahaha

RICER!
