Within the next week i'l be going up to MK to place my order for a kit. I'm going to be using an ST150 engine fitted to an mx5 5 speed box.

I've been up to mk previously and asked about the differences between the R and RR kits however, I'm still unsure on which to go with.

The cost difference doesn't really concern me. I plan on it having a full cage whichever kit i order, The car will be for road use but will do as many track days as possible and road use won't be a huge amount of miles a year.

I had read somewhere (i forget where i saw it) of some people having issues with suspension alignment on the standard R suspension and the adjustability of the RR suspension can compensate for this.

What I want to know is would an RR kit be suitable for primarily road mileage with some trackways, and could someone maybe point out the advantages/disadvantages of the RR kit over the R?

Thanks
Mike

I havnt looked into them.

but if I was buying, id go for the highest spec I could afford, which would be the RR

I guess its like buying a bmw and getting a 330 instead of an m3...

I'd be interested in knowing also, as I might be in the market for a kit soon. So will be keeping an eye on this thread..

Definitely go for an RR. I went for an R and it's been a hassle upgrading it to RR spec, especially the front roll bar and adjustable rear suspension. 13" wheels are also a must, despite the fact that Mk prefer to provide cars with 15" wheels(I presume due to cost and brake clearances, but 13 inch wheels with a small amount of work do fit)

Have you not looked into a mac#1 worx kit ?

I think you will find that Mike is building a Westfield now - unless there's another Valentinik with an st150 and mazda box on WSCC forum!
