Geometry Setup.. Someone Explain Please

[Spiky 37]

ok,

 

had the car setup for tracking today, as i knew it was way out

 

i've NOT fitted my adj tca's yet,

 

here is the results from today,

 

do they look ok????

 

how much more negative camber do i need???

 

[welshpug 1,622]

am I reading that right that there's a tad over 2 degrees of camber?

[Spiky 37]

on 309 wishbones

 

it looks like it

[tom_m 0]

how much do you want? much more than that and it'll become a pig to drive on the road.

[Spiky 37]

thats the thing, geometry isn't my thing

 

hence the post, i need to know what is best for track

 

yeah i drive to track days, but i want the best setup for track

[welshpug 1,622]

down to tyre and suspension choice now I guess, and budget.

[Spiky 37]

well i think i bought pretty good stuff

 

just need it setup right now

[Miles 331 1 Cars]

The set up depends on allot of things, Tyres and make, Spring rates and you, Might be worth getting the Skip brown kit for the back and getting back to a 205 beam

[Spiky 37]

205 beam? why?

 

it will have these fitted soon

 

 

it has these fitted now 185lbs 9" springs, with 300/200 inserts, grp n rear shocks

XMR12 rose joints?

 

I'd grab some seals for those if I were you.

are they? which one's small or large??

 

i'm to not fit covers but put vaseline on them

I'd fit covers if I were you, I used a lot of those exact joints and while they're fine under the light loads I normally use (the PTFE will absorb some muck at low loads), I'd be keeping the muck out on a wishbone because the far higher stresses will cause the ball to grind it into the race before the liner can absorb it.

The joints are cheap though so your choice!

nice bits , but isn't 185 lbs a bit soft for track work?

ok cheers for the info, will sort something out

i noticed a few people bought them,

 

but it's not a major issue to change them and it cheaps.

 

what would recommend???

 

200? or 225? or am i still to soft?

[Garry 1]

I run 300lb and James R used to run 285lb.

 

I have no complaints over my set up, although as you say, it is quite cheap to change them.

[nick 3]

I know it's a heavier car, but Martin (CRF450) is going to 575lb front springs on his 306 track car (1000kg)

[Batfink 201]

My brother used 280lb on a 205 rallye and is was undersprung for track work.

[Sandy 189]

It's relative to many factors, unsprung weight, rear spring rate, ARBs, geometry, tyre type. More than 300lb/inch (or more than 175lb/inch with standard rear bars) on the front of a typical 205, for any purpose to me, is too much. I've driven some appallingly over sprung cars that people thought were good, but I've probably had my standards raised a bit by the best I've driven. A well set up car will be compliant and reap the benefit of progressive and predictable grip in all conditions. Going harder to suit smooth/dry surfaces will bring little benefit for a big trade off in poorer weather/surface conditions.

need to drill the hubs out too thats what put me off fitting mine!

[Rippthrough 98]

Surely they can make a smaller pin if you ask them?

It'll only be a machined EN24 or similar pin anyway I would have thought?

[VisaGTi16v 1]

Hmm I bought some of these but there was no mention of having to drill the hub out, I will ask for confirmation on the buying thread

[Spiky 37]

as i've not fitted mine,

 

kate i assume from this you are talking about he old one's that never fitted with std arb?

 

if yes, then there was no need to say it

 

as you would known these as the new style which fit fine

 

 

and if you look at my post they have been fitted, with ZERO issues with no mods

 

 

i really wish peoople would think before they type and then start a panic, and stupid rumors (not a dig at you kate )

[kate205gti 4]

i bought a set of "rose jointed track rod ends" from comp brake and tried to fit them to my 1.9 hubs, they would not fit i had a lot of trouble and was told i would have to drill them out so sent them back (still havent got my money back for them thou!)

 

i was not aware of any "old type" or "new type" and obviously if i had known that yours were different then I would not have said it because as you say they are different

 

please excuse me for not knowing that they changed them since i tried to fit them - noone told me and i had no reason to know - i was trying to help by forewarning the problem i personally had with mine

 

sorry if i offended by trying to help!

[Spiky 37]

only commented as everyone was say these ADJ TCA would DEF not fit... and hay presto they do

 

thats all.

 

old bad rumors need to stop

 

not offended at all hun
