whiteee 0 Posted September 18, 2004 still wanting to get some porsche wheels... undecided on old school or new scholl yet but wud like some help with fitments... ie. what fits? Maximum width front and rear for 16's and 17's (on a standard height car - but will be lowering on coilovers - nothing silly though!) without arch mods.

Kevin Bacon 5 Posted October 13, 2004 What Porsche rims are you thinking of? RH ZW1s are Porsche wheels and you have to use almost an inch thick adaptor to make them fit a Corrado VR6 with 35 offset. They are 8 x 17. I'm not a fan of wider rear wheels than front ones. For handling they need to be the same width, wider rear wheels reduces grip. Think of an elephant's foot versus a stilleto heel in terms of pressure applied to the tarmac. I don't think Design 90s look right on a Corrado. I'd go for two sets of front 8 x 17 993 Carrera 5 spokes personally, or RH ZW1s. ZW1s..... Quote Share this post Link to post Share on other sites
VR6 0 Posted October 13, 2004 Mmmmm ..... they look nice Kev!! Quote Share this post Link to post Share on other sites
Supercharged 2 Posted October 13, 2004 Mmmmm ..... they look nice Kev!! Yeah, its amazing what you can you with an old set of speedlines, a bit of filler and some polish :lol: Gonna need more than adapters tho to fit them onto that bike :? Quote Share this post Link to post Share on other sites
Kevin Bacon 5 Posted October 13, 2004 It's all in the sanding mate. Give me a chunk of metal and I can sand it into any shape you want :lol: The split rim bolts are fake and just glued on for effect. Quote Share this post Link to post Share on other sites

ving60 0 Posted October 15, 2004 I had 17" Porsche cup 1's on my G60, they were 7x17" front an 9x17" rear an they were fine. I had them lowered on Konis coilovers an it was ok. There currently for sale by the way as i just bought RC's :) Quote Share this post Link to post Share on other sites
Bally 0 Posted October 15, 2004 well done on getting some RC's mate!!! I mailed you y'day mate.. must catchup sometime! Quote Share this post Link to post Share on other sites
OSV 0 Posted October 15, 2004 Here's a pic of the RHs fitted, there are no arch or strut issues, simply bolt on. Quote Share this post Link to post Share on other sites

That's not true, my rear rims are wider and the grip is incredible at the rear, vastly improved, only down side is the car scrubs off more speed in the corners. Noticed how every supercar has wider rear wheels/tyres and F1 cars. Quote Share this post Link to post Share on other sites

coullstar 0 Posted October 17, 2004 Exactly, nothing to do with how the car goes round corners. Quote Share this post Link to post Share on other sites
A20 LEE 0 Posted October 17, 2004 Exactly, nothing to do with how the car goes round corners. Point still stands, bigger tyres more grip. Fit narrower tyres to the back of your C and prove me wrong. Quote Share this post Link to post Share on other sites
whiteee 0 Posted October 17, 2004 Very nice - cheers guys... Im a fan of the twisted five spoke (split or std rim) and design 90's but agree the latter arnt that great on corrados - look great on mkII's and mk1's even moreso... Quote Share this post Link to post Share on other sites
Neil VR6 0 Posted October 21, 2004 Where can you get RH wheels from, they suit the car so well? Quote Share this post Link to post Share on other sites
Kevin Bacon 5 Posted October 21, 2004 There are a couple of UK suppliers but they come out at over a grand, depending on model. You can import them from http://www.mbalurad.de for 1036 Euros + 112 Euro shipping. There might also be a £25 currency exchange fee too, so they will come out at £800ish. And if that isn't bad enough, there may be duty to pay on them too, but not too sure on that one. I know of another place that can send them over for £900 flat, all inclusive. RH currently have no ZW1s in stock, so there's a 3 week turn-around for those at the moment. Quote Share this post Link to post Share on other sites
jedi-knight83 0 Posted October 21, 2004 i didnt realise you needed adapters to run those wheels :? Quote Share this post Link to post Share on other sites
Kevin Bacon 5 Posted October 21, 2004 Yep because the ZW1s are ET60. The adapting rings (hubcentric) not only change the PCD form 5 x 130 (I think) to 5 x 100, but also provide the necessary spacing to to give an ET of 35. The adapters are included in the price, aswells as 8 packs of bolts. 4 packs to bolt the adapters to the discs and 4 packs of grey bolts for the wheels. You will need some short locking nuts and the ones used on the OE VR wheels are unsuitable. The adapters are extremely well made and totally invisible once the wheel is fitted.

Pau1 0 Posted October 21, 2004 Thats a very good price with the adapters included. :shock: Tho i think the PCD on those wheel are 5 x 112 isn't it ? Quote Share this post Link to post Share on other sites
Kevin Bacon 5 Posted October 21, 2004 It might be 5 x 112, not sure tbh. It's so slooooow getting stuff across from germany! It's taken me 3 days to come to a price with the guy from MBAlurad (translation is amusing!), then he tells me RH haven't got any stock and are considering discontinuing it, so will take at least 3 weeks to a month for them to make some and send em over..... worth it though, eh?? :lol: Quote Share this post Link to post Share on other sites

That's not true, my rear rims are wider and the grip is incredible at the rear, vastly improved, only down side is the car scrubs off more speed in the corners. Noticed how every supercar has wider rear wheels/tyres and F1 cars. Not exactly true either, the static grip is the same, for both wide and narrow tyres (of the same compund and pressure) .however a larger contact patch will heat the tyre up less, meaning either more or less grip depending on compound and how hot the tyres were before. What you probably havent considered is the geometry changes you can cause with wider / narrower wheels. The rear tyres on a fwd car dont really do much in the way of accelerating/ braking and so probably run quite cool as all they have to do is corner, wide rears at the back wont increase grip becasue the tryes dont get that hot, however they may reduce it because they end up too cold. Wide fronts would probably help as they do most fo the work, but that brings bigger steering and geometry changes during cornering. Quote Share this post Link to post Share on other sites
Kevin Bacon 5 Posted October 21, 2004 Yep, that's exactly what I was thinking..... and more over, you've got a light back end with very wide wheels so wet weather grip is greatly reduced. Pressure applied to the tarmac is proportional to area and weight. Fat tyres are more inclined to 'float' over a puddle whereas thinner tyres cut through it as the contact patch is more concentrated. A narrower tyred car would definitely have the advantage on fast, wet corners. As said before, it's basic physics. Stilletto heel versus snow shoe......
