I've seen that one thanks James, didn't really want to spend that much but I think I might have to, it is good value. How's the Glanza coming? Do you still have your GT she'll?
I think one thing that goes against them is that one cam is geared off the other making it harder to dial them in and get the full benefits. Couldn't say this is a definite reason as I haven't looked into it much myself. As you said the stock cams do perform well and seem to have adequate lift and duration for a fast road car. I can't recall any aftermarket application getting staggering results for the investment. Would be good if we could get some comparison graphs up.
Check it out https://www.ebay.co.uk/itm/222375601794 Was waiting for them to put pics up as it was stated as being widearched but that doesn't appear to be true. Would be interested to see the bay and interior.
I've been considering one of these but recon I could run into the issue of there not being much room as people mention. https://www.ebay.co.uk/itm/331764941424
