Baz 421 Posted March 16, 2007 You don't really need to space out the front wheels, i wouldn't unless you had hubcentric spacers anyway. 1.6 front setup has a wider track than 1.9's anyway. If anything, you could opt to get wheels in a slightly less offset, gaining a wider stance that way? Thought about using 309 wishbone/shaft setup for the 1deg -neg camber?

Rippthrough 98 Posted March 16, 2007 It's going to be a bit soft at the back compared to the front. Share this post Link to post Share on other sites
david932 0 Posted March 16, 2007 (edited) BazGTMi - i was thinking space out for more steering lock, altho the smaller wheels should help this. also i am trying to get the car to be a bit more even in terms of oversteer. how would i go about getting less offset? 309 shafts and wishbones would have been on my list but i am trying to keep it as cheap as poss(within reason) and concerned about tyre wear. as i already have some on the car that i can adapt i can spend the money elsewhere Rippthrough - what should i do to compensate this? i would prefer the back to be softer than the front for less oversteer brens_1.9_wide_arch - barclays owed me a reasonable sum from overdraft charges. it was money i had never accounted for getting so i thought "why not build myself track car" im have all the tools and am capable of doing all the work myself so there will be no labour charges Edited March 16, 2007 by david932 Share this post Link to post Share on other sites
JamesLumley 4 Posted March 16, 2007 I would do the following... Forget the compomotives - they're heavier than speedlines and not worth the outlay, unless of course you already have them. In which case Ebay them and get a set of std wheels - maybe even 15in speedlines if you're worried what it looks like. Use the std be3 gearbox not the gti-6 box as it will give better ratios for track work. If you've got the box then ebay it and get some extra cash. forget the spacers and stick with the std track width Not sure which exhaust system you are planning to use but check how noisy it will be as a number for 2 1/4 systems are too loud for track days. Most limits are 98db but places like goodwood are sometimes 96! Use the cash saved from the above to buy a decent set of tyres and possibly even a cage. No point in ending up dead if the worst should happen! Then get out there and use an instructor to show you how it's done. I know most people think they're the next shumi but it's worth getting someone who really knows what they're doing to take you out and point out lines, braking points, turning in etc. They might even give you some feedback on the cars setup which is always useful. Good luck! Cheers James Share this post Link to post Share on other sites
smckeown 1 Posted March 16, 2007 Most limits are 98db but places like goodwood are sometimes 96! Are you sure about that ? I've never known Goodwood to be less than 98db. Share this post Link to post Share on other sites

Good luck! Cheers James thanks for your opinion, i havent bought compomotives yet and have the standard wheels so i may just use these instead i have 3 boxes at present a gti6, xsara vts, and a 1.6gti. the reason i was going to choose the gti6 was for cruising to and from the track and 3rd,4th,5th seem quite close which i thought may be good for track altho may be wrong. after drivig back today cruising at 70-80 i am actually quite happy with the 1.6box but may be tempted to combine the vts diff with the 1.6 box. any opinions on this would be helpful. without the gti6 box i suppose spacers wont be necessary. the exhuast is being made by ab motorsport and they have assured me it will be within track regulations i forgot to mention about the cage but i have aready bugeted for this i would be very interested for someone experienced to give me advise and take me out on track(offers? ) Edited March 17, 2007 by david932 Share this post Link to post Share on other sites
Super Josh 4 Posted March 17, 2007 the reason i was going to choose the gti6 was for cruising to and from the track and 3rd,4th,5th seem quite close which i thought may be good for track altho may be wrong 3rd, 4th and 5th in the 6 speed 'box are the same as the 1.6 'box. 6th is the same as 5th in a 1.9 'box, so as you say, good for cruising. For a track car I would use the 1.6 'box or maybe the 1.9 with Mi final drive if you want something ultra short. Josh Share this post Link to post Share on other sites
smckeown 1 Posted March 17, 2007 the exhuast is being made by ab motorsport and they have assured me it will be within track regulations I think you are being a bit naive there, as track noise limitations vary wildly. From the strict goodtood @ 98db to close to 110db. Not many Group N/A exhausts will get under 98db. It all depends on what engine you have and it's state of tune. Also I have a set of superlight OZ Ultraleggeras that are in the pug offset. See the for sale section for details;going very cheap Share this post Link to post Share on other sites

bales 1 Posted March 18, 2007 Carbs seem like a bit of a backwards step on a gti-6 engine, especially when the standard ecu can be remapped to run throttle bodies. Share this post Link to post Share on other sites
jonnie205 1 Posted March 18, 2007 Good spec but dont use a sparco sprint seat, go for evo or corsa etc, much much nicer, run 309 bones and shafts, run pas rack unassisted Share this post Link to post Share on other sites
david932 0 Posted March 18, 2007 Super Josh - may well use the 1.6 box undecieded again about this one smckeown - im not running a group n/a exhaust it's a custom jobby. ab motorsport specialise in rally/track 205s and are a powerflow dealer. i explained i need it under 98db and they said thats no problem. Jrod - is that true? i was told in another thread they would. can anyone confirm this for me please? bales - are you sure about the standard ecu, i've only ever heard of gti6's with itb's running aftermarket ecu's if this is true it may well be an option. i chose carbs as the general setup is more readily available, cheaper and the same sort of power figures can be had if set up properly jonnie205 - i would love to use a nice side mounted seats but i already have the sprints out of my mini, so i can spend the money elsewhere would i need to change the column aswel if i was running a p/s rack?

Jrod 7 Posted March 18, 2007 I think it is but not 100% Can't you just use 1.9 hubs? You do need the lower part of the steering column for the pas rack yes. Share this post Link to post Share on other sites
