steve osbaldeston Posted April 1, 2019 Share Posted April 1, 2019 Just finished my 310S kit which has come with Caterham 14 inch classic 6J wheels and Avon Road tyres. What wheels and tyres should I swap to for my track days. Was thinking:6 inch apollo rims and 185/55/R13 Avon ZZS on front8 inch apollo rims and 215/55/R13 Avon ZZS on rear Can I just do a straight swap or does it need suspension mods.

ScottR400D Posted April 1, 2019 Share Posted April 1, 2019 What size tyres are on the 14” rims? You’ll want to keep the same rolling radius or the ride height’s going to go up and down. Link to comment Share on other sites More sharing options...
StevehS3 Posted April 1, 2019 Share Posted April 1, 2019 There is an easy option of changing the tyres to 14” R888R but 13” are apparently better. I use my 14” for road blats (with a bit of extra ride height) and run 6 inch apollo rims and 185/55/R13 Avon ZZS front and back. I am probably in the minority in preferring same width on the rear.

steve osbaldeston Posted April 1, 2019 Author Share Posted April 1, 2019 14 inch rims have Avon ZT5 185/60/R14 Link to comment Share on other sites More sharing options...
StevehS3 Posted April 1, 2019 Share Posted April 1, 2019 There is the same size available in R888R tyres which would keep you the same ride height and save the cost of new wheels. 13” are apparently better though. I bought a set of 13” Apollos with ZZS for track and I must say they seem great. Link to comment Share on other sites More sharing options...

7 wonders of the world Posted April 1, 2019 Share Posted April 1, 2019 switching between the two wheel / tyre combinations you mention will alter ride height and rake too. Link to comment Share on other sites More sharing options...

Leadership Team SLR No.77 Posted April 2, 2019 Leadership Team Share Posted April 2, 2019 Steve, I'm using the 13" ZZS tyre combination you've stated, albeit with 6" & 8" Anthracites rather than Apollos. It's a great setup for both road and track.My suggestion would be to go for that, have the car set up properly on the 13" wheel / tyre combination, then swap to the 14's for road use ... if you feel you really must! I suspect once you've used the 13" ZZS's you'll leave them on permanently.Stu.Edited for spelling! Link to comment Share on other sites More sharing options...
steve osbaldeston Posted April 2, 2019 Author Share Posted April 2, 2019 Thanks Stu - that sounds like a good plan. Link to comment Share on other sites More sharing options...
