And to further +1 this, I've came across the same conclusion.RattyMcClelland wrote: ↑Thu Apr 02, 2020 10:16 pmUnsprung weight is overrated.
I went from 19kg 20" wheels to 9.9kg 20" wheels before tyre weight on my van and the ride handling was actually worse and Performance difference was unnoticeable. Never noticed a difference on the Prelude either. Tyre weight does make a difference though by compared to contact patch I wouldnt worry.
However further looking into this
The Acura big brake upgrade is as follows.
- Acura RL brake calipers. Same as the late Honda Legend. No where to get them in the UK so import from America only.
- Fatfour customs caliper braker kit
- 350z front brake rotors which are 324x28/30mm (5x114.3). (fatfourcustoms sell redrilled 4x114.3 for 4th gens)
And your chosen brake pad which the legend calipers shares with many OEM applications like Mitsubishi evo etc.
Acura RL brakes and Fatfour custom bracket. There is also another US company that does a bracket, "www.fastbrakes.com", but I couldnt find a specific kit for the Prelude as some americans have told me. I'm guessing they are using an Accord version.
The rotors are a bit more interesting. You can use both Nissan 350z but also the Maxima 2008 model, those could be cheaper to find. (I've read some people have problems fitting the 324 in the calipers, but I actually havent had any real conclusion to this).
And regarding the price, I've actually fitted it in at around 685 pounds, for a nice pair of Acura RL calipers with shipping and import charges from US. Brembo brake pads, the custom bracket, and a 350z grooved 324mm/30mm rotor.
