I can't tell the difference with or whithout a passenger on track. But that's probably because I'm sh*t.

Gary 40 kilos? just on wheels, tyres and hubs? Am I missing something? How much lighter are the A048's?

What you need is to make sure you come to the Hockenheim "High School of Driving" course with us next year.

Don't b*gger your car up just before it again

AArrrghhhhh!!! Fcuk magnesium alloy, 3000 Euros per set!!
Probably i'll take compomotive MO with the same offset of the vxr but in 17" front.

If you are happy to go for 17" fronts – but no Yoko A048s don't forget , then you might be interested in the ATS DTC Motorsport wheels available from Lotus Specials in Germany. They are used by many racing teams.

Front 7.5 x 17" weight including paint 6.6kg
Rear 9 x 17" weight including paint 8.8kg

Price for a set of four = 850 Euro
Price with road tyres from 1690 Euro (Kumho Ecsta) They say they are a lot cheaper than the Yokos, but actually even a little bit better on the Nordschleife and in slaloms.

The steel wheel bolts can also be replaced by studs and aluminium nuts to reduce weight yet further.

These wheels do not need spacers or adapters – bolt straight on.

And if you are happy with your ABS or switch it off on track, you don't even need the upgrade to the VXR version that GM recommend for the 16" fronts.

Lotus Specials say though that there will be a version of these wheels for the Elise, so presumably in 16" fronts (so Yokos are possible again ) – what weight will these be? 6kg?

VXR Speedlines looking like real lard@rses!

Incredible weight and price!!

But rear rim width is really too big, 9" is not good for the standard 225 and i don't want mount tyres over that size


Thanks for info!!

[cicastol]

Check the ATS homepage at :

http://www.ats-wheels.com/


The correct weight is: 7,5x17 9,7-10,1 kg 9x17 11-11,6 Kg

Cheers

Nope – you're looking under the wrong section. Look under the "ATS Motorsport" section.

Dean, my car is already 20-25kg lighter. Have a look inside at the next trackday, it makes the Sprint look plush Corbeau Motorsport seat accounts for approx 1/3 of that reduction.

Yes right,but lotusspecials list only DTM type not the lighter DTC,probably this type of wheels are magnesium alloy,beause they are too light for normal aluminium alloy!!
Seems really impossible to take wheels so light and cheap

look, here list only dtm type:

I think the problem is that they have not updated their site.

A new topic has been posted in the "manufacturers/suppliers" section with this title: "ATS DTC, von Lotus Special mit Tüv" – as they themselves have posted about it, quoting the weights and prices that I have taken directly from that thread, I would think (and hope ) that they are correct.

See for yourself >HERE<

But  rear rim width is really too big, 9"  is not good for the standard 225  and i don't want mount tyres over that size

Sorry, very dumb question, please indulge me. Stock sizes are front 5.5J x 17 and rear 7.5J x 17. How does this compare to inches?

[Thorney]

Interesting. Speedlines have 7j rear size and no rubbing and fine for 225 to 245 width tyre. I tried Oz Lotus hubs which were 8.5j and immediately rubbed the outter bodywork (post lowering via Nitrons) and we had to remove them. I can't see how 9j rims would fit on that experience, maybe with standard suspesnsion but would be surprised on lowered suspension (be it Eibach, Spax or Nitrons). Mind you, these cars aren't exactly identical and what may rub on one maynot rub on another

[VIX]

John, Surely J's are not the same as inches, hence my question? (But I do confuse easily ) Steve

The Lotus Specials Speedster is Oehlins and these rims – seemed to go OK at Hock!

I'm trying to convince myself that the "fat boy" characteristics of the VXR wheels is ok vs the compromises of going with a different (more arduous decisions) set up. 1)The wheels will be stronger. 2)Least hassle way and 16 inch front to take A048's 3)Heavier front wheels = less likely to lock up and throw the ABS into spasm due to small road imperfections??? (grasping at straws here). Realistically how big a difference do you guys think it would make to have lighter wheels? Are they a big no no?

[barrybethel]

Mags Lighter wheels are better all other things being equal. But the vxr wheels bolt straight on and take the best tyres for the car (on track) - the a048. They make a HUGE difference. I doubt if any of us could ever tell the difference in weight just from driving the car or even on the stopwatch. My advice would be buy the vxr wheels and 48's for track days and put your standard wheels on for the majority of your road use. Much cheaper that way and the Bridgestone is imo a better road tyre.

[mags993tt]

Cheers Dean. I do like the idea of being able to swap back and forth with the oem wheels so I think whatever happens I will either get the VXR's or hold out for another simple bolt on solution rather than go down the other routes. edited to say: Does the tolerance on the geo setup mean that one setup would be good for the different wheels or would no mortal human notice the difference?

oooh, missed this thread the first time round. Love the VXR wheels on your yellow car mate My LY wheels were a bit mashed up by tthe previous owner and this would be a much more desirable solution than paying £100 per wheel for refurbishing. (ha, as if I'm ever going to have the money or get around to refurbing the wheels anyway!) Nice one
