Greetings

Watched quite a few videos from that website. It's weird how oldschool has become the new school, if that's the right way to put it. Bike trials has clearly evolved in such a direction that it's made room for this kind of riding to return not just on it's own, but along with the type of bikes that were used 10-20 years ago. So it's ideal really, each of these can evolve on their own and we viewers get double the entertainment in return.

It was making the whole forum a mess. All the typos and seeming text talk in NMC wasn't the members' fault, their keyboards were becoming sticky. All because of one silly thread. They took it down, NMC no longer needed. Point proven. edit: Matt, please no, I don't want to have to leave this forum for the next few days until things run quiet (hope it doesn't take that long)

You wouldn't so don't expect others to

Gf has been working out for the last few months and she's getting so fit I find myself drooling all over the place. Happy times

Seemed to me like a joke until I finished reading the first page, some people "pretended" to take this way too seriously.

They probably aren't going to change the world considering their website clearly states that they are not real. Just click here: http://huvrtech.com/legal.html And scroll down.

That's a fantastic idea. I generally don't like comps but something like this I would take part in with great pleasure.

Sounds like it Probably for GTR cars though. Went to the workshop which will remove some 250-50 and 180-70 springs off a racing M3 for me, saw this in the parking lot: Seems like an ordinary M3 until you look at the instrument cluster.

Well my rear springs are 120Kgf/mm which is so completely wrong it's actually funny. How can AST make such a mistake. It's a bit like building a stock bike up on 20" wheels.

Urbans are the only V forks Echo make so it's kind of self explanatory.

Never seen an Evo thrown around and driven with so much hate before: http://www.youtube.com/watch?v=OxNo3tKRcjQ Absolutely amazing driver.

I do it to all Daihatsu Charade G102 owners I encounter. So far, in the past 1,5 years it's happened once and ended up in rather a lengthy conversation. Rare car, looks like a piece of crap but is actually brilliant and only owners know that.

Edit: Scrap that too Feel thick like a brick today. Like you say it's 80N/mm. Got lengths and rates mixed up haha So yeah, it seems the front is 142cpm / 2.38hz left and 174.25cpm / 2.9hz right. Yeah, I'm going to weigh it again, the differences between left and right are staggering. Would 2.38hz not be ok for a bumpy tarmac road? Edit 2: Adam, for future reference, would the suspension ratio on this carrier be 1:1? The coilover mounting points are at the bolts sticking out from near the hub. I would have thought that the suspension ratio should be measured from tyre centre to pivot and from coilover to pivot. Is this right? That calculator you sent seems to say that for a Macperson strut, this is 1:1 so they are not accounting for wheel offset etc.

Thanks a lot Adam I've played around with the calculator and must be doing something wrong. I'm assuming this calculator works on 1 wheel at a time. So I've started with the front left wheel. 401kg load on that wheel, the spring is a 180Kgf/mm judging by the 180-80 markings and unsprung weight I'm assuming is around 50kgs (20 for the wheel, 30 for the rest). I'm guessing the leverage should be around 90% so I've entered 1/0,9=1.11) and got 610cpm which doesn't sound right judging by the figures you mentioned? What am I doing wrong? edit: scrap that. Seems the calculator is either a bit faulty or kgf/mm is not the same as kgs/mm. I've converted 180kgf/mm to Lb/in which is 15.62 and entered that into the suspension calculator. That converts the value to 0.28 kgs/mm. Anyway, with that in mind, I'm getting 24cpm.

Depends what you want to calculate surely? I'd assume some pretty advanced maths needs to be applied to actually calculate spring rates from scratch. One would definitely need to start off with a perfectly mapped bumpy surface resembling a special stage, work out the leverage of the suspension, centre of mass, load on each wheel, ARB stiffness and lots of other variables/constants and then match the spring rates to the desired suspension travel on that surface. Result is bound to be a multidimensional graph. Sounds like a job for F1 teams

If only I knew how Thankfully my friend needs racing springs and currently has springs which he used in rallysprint. So we just need to swap them over.

I'm not buying off the shelf springs though. I send them information about the load on each wheel, intended use and expect them to send me the right springs :/

Turns out my rear springs are the same ones my mate has on his M3 GTR. I wonder how thick people at AST must be to think these will be ok for tarmac rallies.

Your brakes sound exactly like mine. This feels really weird to watch.

There's not going to be a war, that's what I think. I do find it absolutely disgraceful that the US is the only country being strict about this and the EU couldn't care less. Something worrying happened on Friday evening or Saturday morning and the EU decided to hold a summit for foreign affairs ministers on MONDAY. So clearly a situation which could end with war is not worth discussing over the weekend...

It's all custom, I'm guessing they might have forgot this is a tarmac rally car, not a race car. Got to get the geometry set up and I'll try to work on various damping settings. Thanks for the help

Cheers. Haven't had the chance to play around with it too much, found it to be at it's hardest setting so reduced it to 3/8 but it still felt odd. I guess that with 8 settings it's not going to take too much time to belt down the same bumpy road 8 times with a different damping setup each time. However, I'm guessing that if the spring rates are indeed too hard, it could be impossible to set the damping up so the car doesn't jump around?

According to the website: "1 way adjustable in rebound damping ('Singles'), " So I guess it's only rebound, not a setting which works on both rebound and compression.

Finally got AST coilovers on the rear. I've only had a short drive on these but they feel really odd. I'm pretty sure judging by how the engine sounds that the rear end of the car is bouncing around. Presumably if the springs are too stiff, there's not much one can do with damping, right?
