Minilites or Rewinds for Vixen
Discussion
I'm looking to order a set of Minilites for the Vixen, to be shod with a set of road legal track tyres for use on track - probably Yoko AD08R.
I haven't yet decided whether to stick to 5.5J or go to a 6J rim. I plan to run either a 185/55 or 195/55 profile. Has anybody been through this process and therefore offer advice to avoid any pitfalls.
Thx Moto

That's fine as these will be track only tyres/rims. The smaller circumference will mean acceleration should improve but also it will reduce roll through the corners. As there are unlikely to be potholes etc the lower ride height should not be a problem.

How will the smaller circumference reduce body roll, through corners? Moto

What does an Anti-Roll Bar do then!!!!!
The clues in the name
I am replacing the std 19mm arb with a 22mm as the main way to reduce body roll.However I was hoping to get a heads up as to whether anyone has tried 6J Minilites (with 185 or 195 55 profile tyres) on a Vixen and whether rims & tyres clear the suspension and arch ok, especially on full suspension and steering travel. Also does anyone know if longer wheel studs are required with Minilites. Or any other problems people have hit when going this route ?

If you take my Tuscan as an example this is the size and off set that i use on the wires using 205/70/15 tires i run a 5 mm spacer although its not really needed no clearance issues i have shaved the inside of the wheel arch edge on the back slightly as i found that driving hard when she lands over rises the Tyre was just touching on compression
Hope that helps Vixen measurements will be the same

Clearance will differ depending on wheel offset. I'm presently looking for some wheels to suit my S2 Vixen.
What offset are people using with 6J wheels? The TR fitment is aroumnd ET8 with a 6J but the Vixens used an ET -10 or thereabouts.
I can't find anything off the shelf which gives a negative offset.

Pictures paint a thousand words as they say! There is a reasonable image here : https://www.suspensionmaxx.com/tech-support/wheel-...
As has been said it refers to the relative position of the mounting face to the centre line of the tyre mounting area.
ET0 means that the mounting face is on the centre line of the tyre, ET(+)8 would mean that the mounting face is offset outwards by 8mm which in turn means the tyre would sit 8mm further into the car. ET -10 would mean the opposite which would push the tyre outwards.
The vast majority of cars use a positive inset value (ET15 to 45), some of the older RWD cars have lower values but again mostly positive say ET5.
All this is independent of rim width. Backspace is the resultant combination of width & offset plus is generally the important factor when trying to judge if the wheel when fitted will clear chassis, brake & suspension components. As an example a 5.5J wheel may have an overall width of 170mm. If it were ET0 then the centre line would be in line with the mounting face which would give a backspace of 170/2 = 85mm.
If it was a 7J rim with a width of 205mm still with an ET0 offset then the backspacing would be 205/2 = 102.5mm.
If the offset was ET10 then it would be 205/2 = 102.5 +10 = 112.5 backspace.
If the offset was ET-10 then it would be 205/2 = 102.5 -10 = 92.5 backspace.
The older TVRs are a bit odd in the fact that they have a negative offset, ie ET -10. Not many cars use a negative offset as it does put additional loading on bearings & suspension parts plus can give some odd suspension geometry.

Running 6J Compomotive MLs in my Vixen with 195/65 tyres with no clearance probs. I have got Exactly rear uprights on the car and use no spacers, I'm sure Minilite can supply something similar. Geoff
Geoff,Thanks, that's useful info. I presume the Exactly uprights are pretty similar to the standard units, in terms of potential for interference with rim/tyre?
Do you know what offset / backspace your rims are ?
