If you say it was stable, then it was mate :)

 

I've always been dubious about bonnets not being shut properly and with my carbon bonnet, even being shut you could see the air lifting it at the front corners (no pins were installed at this point).

Next time you see a bit of in-car footage from a race have a look at how much the bonnet bends and flaps around on those cars. They look like they are ready to undress!

I need to get some lighter wheels for the track. Not concerned about looks I just want the best setup to go with my Ikeya bits. I am really not sure where to look. Would 17" be best if I can fit them over my brakes. I would consider getting some made to get the best suspension,wheel and tyre combination. Any ideas?

Image Wheels could do some with custom offset and correct spigot hole size, you want to try and avoid spigot rings. Most of the Jap aftermarket rims are heavy, even the expensive magnesium stuff from Rays comes with a generic spigot hole size and adapter rings :( You will probably need 18 inch to run anything like a big enough brake package. Choose the tyres, then the rims. What brakes will you be using and what's the estimated wet weight of the finished car? If you have a big budget you could have centre lock hub adaptors made and run 19 inch touring car centre lock magnesium rims, which can be picked up cheaply.

I was looking at 18" as the choice of part worn slicks available at the right price is much greater, getting slicks in 17" is not as easy these days.

 

The Advan Racing that the Whifbitz cars use would be my first choice and dare I say it, they look good too :D

 

If slicks are not your thing then a set of 17" that go over your brakes are more than enough, I have been and still do run 17" on stock sizes and never have traction issues when using decent rubber.

Also remember that on track with a decent ECU its better to tune your power to the grip level, this will at least give the TC a chance if you are using it, loads of unusable power is only of use if drifting and wanting to break traction.

 

Gear/Speed based boost control can do wonders for traction, keep the power just above the grip level and then use a little TC :D

Thanka Wez, I did look at Advan 18" but the off set is low. I am sure Chris would say best to get wheels as close to stock offset as possible for optimum handling. If I am putting £6K into suspension, I want to get the optimum handling so wheel choice is really important, hence considering custom wheels in the absence of an off the shelf option.

 

I am hoping that Ryan will sort out some good maps on the Saves for me.

Once you get all the compliance out of the suspension you can be a little more adventurous with rim diameter and offsets in a race environment. Wheel bearings being tiny and front uprights being floppy means you have to think of loadings though. With road cars with easily overloaded hub bearings and floppy uprights it's a compromise.

This is something I've been looking at but not quite come to a decison yet

 

http://www.wheelweights.net/ is a useful starting place to get the lowest weight wheels in different sizes.

Thanks Chris, I must have missed your post when browsing on my phone. Very interested in the centre lock approach, what sort of money are we talking about, any links appreciated.

They would have to be one off, *BUT* if my wishes come to fruition and finances allow, I am seriously thinking of using them on my Skyline to allow me to use super high quality mag wheels at a low cost per wheel rim. I envisage 4 adaptors for a given rim type being about £1200 as one offs. Here's a site seeming to offer something commercially, I would not want to be tied to their wheels though:

They exist, but are not very common, but wheels can sometimes be bought undrilled.

 

I assume the only only undrilled ones are going to be new, so loosing the cheap wheel option. Or is there an option with the adaptors to have locator lugs with a different pcd to the standard fixings? All the ones I have found, some cheaper than £1200, are matched pcd.
