TRACKDAY TYRES

[Mark_Ritchspeed]

Also (for Northy) got some Yoko prices as well.

195/50/15 AO48's semi-slick in either S/SS/Med compound are either £220 for 2 (delivered), or £410 for 4 (delivered).

A006T 190/580/15 (basically 195/50/15) which are FIA approved cut-slick tarmac rally tyres work out at £260 for 2 or £500 for 4.

And, if your going to use either slicks or semi-slicks you really will need some serious suspension work to get any gain from them.

mark is there any point with them 200lb springs i will be using? only after the front road legal tyres, semi slicks

[Mark_Ritchspeed]

Yes the springs should be fine, but to make sure the outer edges of the tyres dont get destroyed you'll need some negative camber, which I now have.

The only problem I have now is I need to get a shorter 16v driveshaft as the hub is sitting in closer to the gearbox and clunking on the inner joint.

as std it runs about 1degree neg camber on both front wheels ill have to buy some camber bolts to get more lol :D

[Mark_Ritchspeed]

Thought about camber bolts, but just heard too many horror stories on different cars, so decided to slot the top hub-mount on the strut. Which enables you to have adjustable camber, but without having to use thinner, weaker bolts.

good idea, i was on about this to rich the other day!

'goes to find drill'!!

[Rich]

how did you slot them mark? did you just 'file' them out shall we say? any stengthening plates?

[Mark_Ritchspeed]

At the moment, they are just reamed out to a 15.5mm hole as opposed to the 12mm hole as standard. This has enabled about 1.8 degrees neg.

I may take them out a little further (16.5-17mm) and get them to exactly 2 degrees, give them a good test and then weld washers onto the struts for extra security.

[Rich]

ahh right thats cool then, i need to take some negative off my drivers side so i need to look at the bottom hole i presume to have the opposite effect? something is wrong but i'm not sure what on it as its about 2 degrees out compared to the drivers side gonna see if the ball joint is the correct size first though before i touch the damper leg

[Mark_Ritchspeed]

Wrong strut maybe? Lots of the Renault struts seem to have vastly different camber settings on the hub mounting.
