Mavic82 Posted August 15, 2013 Share Posted August 15, 2013 So I like the 16" HPC wheels. If set up right drive great and IMHO look great to. The problem is they weigh to much. So I will be speaking to Harry at Image about making some lighter split rim replicas. Anyone else interested as it may reduce the part price?

Area Representative gileshudson Posted August 15, 2013 Area Representative Share Posted August 15, 2013 Definitely . . . as I love the style too, as you know 😬 I only deserted mine for the Caterham 15" wheels due to a lack of available soft rubber for them. Now that you can get super soft Toyo T1-R and T1-T tyres for them I'd definitely be up for this to get my beloveds back on Beryl. Link to comment Share on other sites More sharing options...
Leadership Team SLR No.77 Posted August 15, 2013 Leadership Team Share Posted August 15, 2013 Surely they'd be better in 15" though to maintain the better handling and availability of tyres Or 13" .... a split rim 5 spoke with a Caterham locking full centre cap would be fantastic It could be loosely referred to as an SLR 5-Spoke Stu.

Area Representative bluenose Posted August 15, 2013 Area Representative Share Posted August 15, 2013 I have both MB Split Rims and some Image split rims, both around about the same size in width and 13" and the MB wheels are so much lighter, although the centres are magnesium. Worth getting him to give you a figure for how much lighter they are going to be. Nick Link to comment Share on other sites More sharing options...
Leadership Team SLR No.77 Posted August 15, 2013 Leadership Team Share Posted August 15, 2013 But was the MB not designed/specified at a weight that ultimately deemed them to be not fit for purpose .......? Stu. Link to comment Share on other sites More sharing options...
Area Representative bluenose Posted August 15, 2013 Area Representative Share Posted August 15, 2013 There are two versions of the MB wheels, the later version is a different casting and as far as I am aware has not failed. Both versions look similar but the thickness of the castings are different and there is the initials MB cast into the newer stronger design.

I think the reason that Guy raised this about the existing 16" HPC wheel (and he and I have chatted a lot about this) is because the wheel exists already and has a beautiful simplicity & elegance to it, as well as filling the rear (and front) arches so nicely. This could easily have been posted in the Bulk Buys folder to sound people out on a lighter split rim 16" HPC replica wheel, although it was interesting reading yours and Nick's comments above as I welcome anything that leads to the lightest 16" wheel possible when all the options are looked at. 😬 Edited by - gileshudson on 15 Aug 2013 13:17:11 Link to comment Share on other sites More sharing options...
Leadership Team SLR No.77 Posted August 15, 2013 Leadership Team Share Posted August 15, 2013 My 13" was more a tongue in cheek comment ... the HPC, SLR and Prisoner wheels are all from a similar era and all had the full wheel centre that hid the wheel nuts, the SLR and HPC both being simple 5-spoke wheels but in vastly different sizes. However ..... IMHO sticking to a 16" will undoubtedly limit demand with a 15" resulting in far more interest. At one time I did run my (old) car on HPC wheels but would avoid doing so now. Stu.

Mavic82 Posted August 15, 2013 Author Share Posted August 15, 2013 Guys, I want to avoid the debate of handling between wheel sizes. If a car is set up to work with a given wheel size it will work well. You need different geometry, spring rates and damping you can not just unbolt one and bolt on another and expect it to work. I would not change from 16's, if I really had to I would go to 15's but I simply do not like the feel (or look of 13') my car drives and handles very well on 16's and with the toyo r1-r sticky rubber is not an issue. So anyway if you are interested let me know, if 15's are also of interest I will take note for those to. I will check the weight issue as this is the main point of the change to reduce mass and inertia. Regards Guy Link to comment Share on other sites More sharing options...
Chris Cardwell Posted August 15, 2013 Share Posted August 15, 2013 Also interested in alternative 16 inch wheels Edited by - Chris Cardwell on 15 Aug 2013 19:20:26 Link to comment Share on other sites More sharing options...
Paul McKenzie Posted August 15, 2013 Share Posted August 15, 2013 ISTR going from 16" HPC's to 13" MB mags saved me 8-9kg per wheel/tyre ....which is not too bad if the objective is to save mass and inertia Link to comment Share on other sites More sharing options...
combine Posted August 15, 2013 Share Posted August 15, 2013 My 16 inch original wheels and tyres are stacked up in the garage ! Those Avons are designed for normal cars not lightweight sports cars ! Link to comment Share on other sites More sharing options...
Mavic82 Posted August 16, 2013 Author Share Posted August 16, 2013 The weight and inertia is the reason for the change. So if I could save 30kg and move the balance of mass toward the centre that would be a great result. Link to comment Share on other sites More sharing options...
GF04RCE Posted August 16, 2013 Share Posted August 16, 2013 You could always go for wire wheels Turrino Wire Wheels I have been meaning to talk to Will and Ken (father-in-law) about weights, since they hold the patent for split rim wire wheels. Means you can use Ali outer with Steel centres. I am wondering if with such a light car if they could make a lightweight special (fewer spokes) for a seven. alot of what they build is for racing and they pretty much can build anything people ask of them...Split Rims are great as it makes it very easy to build different widths of wheel... Because of the unsprung weight advantage ( fuel economy) we were talking about putting a set on my BMW as a test mule. I'll have a chat with Ken at the weekend and get a set of scales out... and see if maybe they can do a seven set for testing....worth a try!! Does anyone have a list of standard weights for the Caterham 13"/15"/16" wheels plus the Mags, without tyres...?

jackb_ms Posted September 5, 2013 Share Posted September 5, 2013 any ideas of cost yet? Jack Link to comment Share on other sites More sharing options...
Mavic82 Posted September 5, 2013 Author Share Posted September 5, 2013 I have spoken to Image. Standard prices for a 16" billet split rim is around £340 per wheel. They have two wheels in their current range that are quite similar already so i am planning a visit in a few weeks to see them in the flesh and see whether these match with minor changes or whether a new design would be required. If that were the case I suspect the cost may increase but will know more then. Will advise when I have further info Link to comment Share on other sites More sharing options...
