calZ Posted March 21, 2022 Share Posted March 21, 2022 If the pedal travel is too much, just upsize the master cylinder. Quote Link to comment Share on other sites More sharing options...
AydinZ71 Posted March 21, 2022 Share Posted March 21, 2022 (edited) Agree with Calz. I’n theory, the travel of the pistons is proportional to the pedal travel. Unless the rotor is warped forcing the pistons further away from the rotor. Il be honest, I don’t have enough first-hand experience to know if a single sided caliper makes a big difference but I would look to other solutions first if this is the only concern you have with the OEM calipers. Braided stainless brake hoses, bigger master cylinder, check rotor trueness, etc. PS: larger master will require less pedal travel but increase pedal pressure required. May not be noticeable with properly functioning brake booster. Edited March 21, 2022 by AydinZ71 Quote Link to comment Share on other sites More sharing options...

I have to drive more now downsized rear brakes. Before it felt like rear already started to bite and front were still closing gap away from pads. Maybe 1" on front and 23.8mm to rear master would help. I have new rotors on front, zero wobble. That doesnt mean they are straight Edited March 21, 2022 by manninen Quote Link to comment Share on other sites More sharing options...
manninen Posted May 16, 2022 Author Share Posted May 16, 2022 Summer getting here, took it on drive after modifications and smaller rear brakes seems much better, braking on a corner rear stays stable. these 185 width tyres doesnt have much grip on full abs braking but ride is nice for 240z.

manninen Posted June 7, 2022 Author Share Posted June 7, 2022 (edited) https://i.ytimg.com/vi/kyKNIlYgUjI/maxresdefault.jpg im so tempted to try these tyres, probably would ruin ride quality Edited June 7, 2022 by manninen Quote Link to comment Share on other sites More sharing options...
manninen Posted July 3, 2022 Author Share Posted July 3, 2022 (edited) https://xfelgi.pl/tomason-tn1-45x14-4x1143-et10 In finland we have mopedcars, one cylinder diesels so youngsters can drive them with moped driving licence. Found mopedcar rims 4x114.3 et10, its direct fit to rear axle, front needs to turn lil bit larger. but guys, 100€ for wheels which weight 4.5kg!! that polish site says wheel is rated 580kg. hope its true. 100€ cheap price for own death Edited July 3, 2022 by manninen Quote Link to comment Share on other sites More sharing options...
manninen Posted July 5, 2022 Author Share Posted July 5, 2022 (edited) these ride very nice, except 2 of these hankook tyre aint round. i dont have good luck with tyres. i need to stop ordering tyres online. i took couple full throttle runs, 185 tyre burns so easily, i had to tightened rear lug nuts after. 5 lug hubs might be good idea as well.

manninen Posted August 24, 2022 Author Share Posted August 24, 2022 (edited) i did custom engine support bar today, i oil pan leaks that much i have to fix it. maybe i have to do new carrier for external oil pump too, real drysump would be nice as well but theres no room for those things. Last week i was on vacation with Z, 640km, no issues. Edited August 24, 2022 by manninen Quote Link to comment Share on other sites More sharing options...
manninen Posted September 26, 2022 Author Share Posted September 26, 2022 Here is my oil pump, this thing is heavy! i could get huge weight savings using aluminium oilpan and singlestage automotive pump, but this has support bearing and doesnt seems to care little higher rpms.

manninen Posted September 30, 2022 Author Share Posted September 30, 2022 (edited) https://i.imgur.com/zvTZsoE.jpg as i have occasional steering wheel shimmying, im running stock bushing. i have full PU bushing kit. Is this 100% safe way to try if shimmy comes from soft bushings?with stock bushings compression rod moves really nice, pu on fron rubber rear, pu bushing moves a bit on its place and makes some noise on rod moving. whats your thoughts? im thinking just try lil bit harder rubber bushing on front, maybe some other brand oem bushing Edited September 30, 2022 by manninen Quote Link to comment Share on other sites More sharing options...
