Wheels

Just out of interest, does anyone know what wheels they are?

Also with regards to the Lotus S2 111/S. What characteristic changes do you get between the standard wheels on the S2 111 and the motorsport wheels? I presume the motorsport wheels are heavier?

I know this may seem somewhat open question but for those that know, humour me

That is a Lotus "esthi" - a highly modified and widened car with a 2.7l twin turbo audi engine. It weighs around a ton, has much wider wheels - 17inch front and 18inch rear. They were running 235 fronts and 275 rears!

You won't be using those on a standard elise.

Yes, Im fully aware of that car and what it is.

My question is: looking through the adverts some Elise’s have the OZ motorsport wheels on and I was wondering about the handling characteristics.

And, what wheels are they?

You can find them here name and all...its in German and all for Lotus Elise/Exige

Look under "felgen" on the left side 3 options with rims, the second are with the OZ rims.

the ones from the Esthi are Oz F1 Racing




I also put the link under the faqs!

OZ motorport alloys are what they fitted to the 190 and 135R.... otherwise available as an accessory. Basically they allow a wider front tyre for K series S2 and are lighter and stronger (std wheels warp easily). 111R's wanting wider tyres often run the forged or exige wheels. Other wheel option require hub adapters.... you can ofset the weight of these with ali hubbed brakes but non-lotus wheels are not popular in the UK, though the mainland euro owners love different wheels!!

If you want to see pics of OZ motorsport alloys then check the pic of my 135R in my profile

Typically OZ's cost about £1k then tyres.... most run A048 Yoko's or 888 Toyo's. You'd need uprated susp to benefit from these tyres.

The best resource for Elise wheel data and comparision is the "wheels & tyres" section of www.hubspace.net

I was not trying to be rude, sorry, I got called before I could write the rest of my post (in A&E). I have never seen those particular oz wheels on any other car. The esthi also had the oz super leggera in 17 and 18 inch. These are more similar to the oz's that are "off the shelf" for the elise. As has been said, the oz's from the 135R fit onto the standard hubs with no spacers required. Generally these are used as a track configuration running the yokohama 048 tyres. The front rim on the oz is a 6.5J and hence accepts the 195 front tyre without major overhang. The oz's (motorsport wheels are lighter than the standard wheels despite being wider. Can't remeber the exact figures though.

I run both standard 111s wheels for the road and oz's for the track, so may be in a position to comment. The 048's are really soft, wear out fast (4-5K miles) and are not good in the wet or when cold. When they meet standing water they are very dicey. I had two slides on the way to Donnington on icy rods while driving with hbaumhardt who was on standard tyres. He was unaware of any traction problems on his car at the same speed and route in convoy. On the other hand, on the track, with heat in them, they are awesome. Huge grip, great turn-in really progressive, no understeer etc. Brilliant tyre, really forgiving.

The road tyres - Bridgestone or yoko AD07's are far better in the wet and last longer. A little more understeer which is easily controlled, but good all round tyre / wheel combo. As a daily driver, I would not use the 048's - high wear / lack of wet grip / cost etc. Also, it would not be a great idea to run the 175 fronts on the 6.5J front rims (the tyre would be a bit skinny) Conversely, 195 tyres on standard rims may be pushing it. Also, going to sticky rubber (048's or toyo 888's) means a suspension change as you may be hitting the bump stops on the standard suspension on hard cornering, which is not recommended. The steering on the 195 tyres is a lot heavier at low speeds.

There was an excellent thread titled S2 understeer recently. I hope that helps, sorry if you took my original post as insulting your intelligence - it wasn't meant that way.

Hey no problems. Thanks for the insight into the differences

[steveb25]

AF07?

I've never heard of these and cant find them on a google search.

Would be very interested to know about them though as My A048's need replacing and I cant afford to replace them with the same tyre as they wear to fast and I do mostly road driving.

Anyone got first hand experience of Toyo T1 R's???????????

OR

Anyone got any alternatives that I could put on?

[shangani]

Sorry, typo error - Yokohama AD07's - the official new lotus tyre for 111r etc, replacing the bridgestone. Has been on the federal elise for quite a while.

[Esprit]

T1-s are a good choice on an Elise..... Probably not as good as the new AD07s but a darn site cheaper. I run T1-Ss on mine (superseded by T1-R) Based on my experience with T1-R shod elises the R is a step on from the S in terms of longevity and grip.

Neither will be a patch on the 048 in dry conditions, or on any track that doesn't have standing water.

I've got the dilemma of choosing the nex tyre for my S1. It's a trackday car and a weekend toy rather than a daily driver, fully standard suspension and all. I'd keep the road-tyre, but I'm now pushing it so hard at the track that I'm scrubbing the tyres so much that their life is only about that of the average track tyre. We'll see though, I've got a while to decide... my car's never going to be a dedicated track car, I'm hoping to have an S1 Exige in a year or two to take over that role

[polus]

Presumably if you had the wider motorsport wheels on rather then the standard wheels both wearing the same rubber/tread (except for a different profile) - the wider wheels would have more suface area so in the wet they wouldnt be as effective at clearing the water from the tread as the standard ones. Presumably in the dry they would perform better however loosing grip on the wider wheels/tyres would be more sudden the the standard wheels.

Is this correct?
