EEK Posted July 30, 2019 Share Posted July 30, 2019 Anybody aware of any potential issues in fitting Hispec 260mm solid discs along with their Ultralite 4 Caliper to an S3 (1998) shod with either 13 or 14 inch wheels?i.e. Any clearance issues?

Mike Biddle Posted July 31, 2019 Share Posted July 31, 2019 I have 280 MM Hi spec discs and and racing 4 calipers. I am running 13 inch rims, so you should be OK, but that would depend on rim and caliper design/dims.You should be able to check by getting the caliper dims and measuring clearances on the car.

EEK Posted July 31, 2019 Author Share Posted July 31, 2019 Mike - thanks for this - challenge is I'm in France and car is in UK and was hoping to get them to fit when next over in case it's raining and I am stuck in the garage. I have the drawing from HiSpec so perhaps will measure this next time and get them for the time after.I am sort of guessing that the design of their caliper allows for the bigger disc while fitting in the same overall dimensions of standard fitment.Caterham-260x10-UL-lug.pdf Link to comment Share on other sites More sharing options...
SM25T Posted July 31, 2019 Share Posted July 31, 2019 The Ultralite 4-pot caliper can be used with 232 or 260mm discs. There is quite a big gap between my caliper and 15" wheels, so I am sure you'll be ok. Be aware that the lead time from HiSpec may be a week or two ?

TomB Posted July 31, 2019 Share Posted July 31, 2019 I have HiSpec UL4 fitted for the standard front disc. Would it be a simple case of buying the bigger HiSpec disc and swopping over or is there anything else that would need modifying? Link to comment Share on other sites More sharing options...
SM25T Posted July 31, 2019 Share Posted July 31, 2019 I didn't do anything special when I fitted my 260mm Link to comment Share on other sites More sharing options...
