And so it begins....................

I have 235/40 18s for my 888 rears. 235 x 0.4 x 2 = 188mm, plus 18 inches = 457mm Total diameter 645mm.
You have 265/35 18 for your 888 rears, so 265 x 0.35 x 2 = 185mm, plus 457 = 642mm diameter.

My only issue with mine was when my ride height was too low, so do check ride height if these catch on the outer edge on the wheel arch. Its the width that may be the issue. What's the offset of the RL7s?

I bet the tyre catches the outrigger . We spoke about it before ,you could cut a section out and replace it with flat steal .

[phazed]

Just done a road test, went around the local roundabout as fast as possible many times,, no catching as yet!

Good news. That's the biggest risk dispelled. Now try a few roads with bumps or dips, to compress the dampers and bottom out the suspension.

Nice boots Peter, that's one hell of a footprint you've got there mate.

We'll have to start calling you The Yeti

But unlike certain under-powered over-tyred smaller BMW's Peter's car can actually use them

The last 2 posts have confused me, I'm easily confused.

Ah, must have been the cold buffet and the glass of wine

Will still struggle for traction on the dragstrip
Got to be good to dip into the 1.7's and nudge into 11's tho.... respect

Looking forward to seeing how they perform in a week's time...

[phazed]

Getting a pair of 235/40/17s for a pair of front RL7s next week.

Hopefully will compliment the rears nicely.

With a bit of tyre changing that will leave me with a set of R1Rs from my Image wheels on a set of 17"x8" Rl7s for the road set.

That picture plays tricks with the eyes. I was certain that there was more than 20mm difference between those two tyres, but then I put the image on a big screen and actually measured the tyres, and that's all the difference is. Weird.

[Sardonicus]

Trouble is there appears to be no exact figure with tyre widths I have seen 225 tyres that are more like 245 when fitted to approved sized rims and those track tyres are a good example of this they often come up wider than is quoted even road tyres Goodyear NCT 2's are one I remember 205's when fitted to a 7" rim they was more like 225

Little bit of work today. Fitted an Elise seat that I had in the loft for next weeks TD. Made good around roll bar and fitted back carpet.



Made up and fitted guttering splitter.



Ride height is 170mm at the rear and needs lowering 10-15mm. I'll test at Snetterton first as is.



Bloody eck, them magnetic tyres work well!

[QBee]

Might the ride height have been affected by turning the car upside down to fit the splitter?

[SILICONEKID343HP]

Just measured my new rear Federal RSR`s road legal track day tyres ,they are 235/45/17`s and wider than the Falken 452`s 245/40/17.

Work that one out!
