yellowss7 Posted September 16, 2007 Share Posted September 16, 2007 WoW! Took the Beast out today for a little Blat. Changed over from 10 inch Hoosier soft compound slicks at all for corners, to Avon CR500's street tires. Got about a mile into the drive and a nice little right, left off camber combo is clear, so I take it accelerating through it. :willy: :willy: :willy: Car does a 4 wheel drift into the other lane. :surprised: No drama, flick and its back on track. Good thing I could see the lane was clear before I started. Cold tires, too much power and forgeting that the car on slicks drives slightly differernt. :smash: Felt good to drive more than 60 seconds at a time. Just miss the slicks!!

James A Posted September 16, 2007 Share Posted September 16, 2007 I use CR500s for the street, and they are about as good as it gets for that use. But in autocross on say, a 60 second course they would be on the order of 2 - 4 seconds slower. If you get on some wet pavement you won't miss the slicks. I drove home on some ACB-10s one day and got into the aftermath of a thunderstorm, not fun! Link to comment Share on other sites More sharing options...
scannon Posted September 16, 2007 Share Posted September 16, 2007 The Avons should get better after a few hundred miles, new tires generally have mold release on them and are quite slippery at first. Link to comment Share on other sites More sharing options...
gjslutz Posted September 17, 2007 Share Posted September 17, 2007 I have a new to me Birkin with 15" and need the height for the street, so 13" are not an option. It came with a extra set of 225/50X15" KUMHO V710's that stick, but as expected pick up everything & shower the car with sand & micro stones. What would be the best grip for dry with a little wet driving. I think the largest I can use is: 225/50 X15. It presently has 195/50X 15" Firestone Firehawks that are a little loose for me.

Al N. Posted September 17, 2007 Share Posted September 17, 2007 How many people here have run DOT slicks on the road? You know, those ones with a few grooves on them to satisfy the letter of the law? Link to comment Share on other sites More sharing options...
Boxologist Posted September 17, 2007 Share Posted September 17, 2007 nearly all R Comps will have some sort of tread. most will get shaved. a few tyres are tread free. but an R comp will wear faster, and as Tom has learned, instill a confidence at taking the 7 to a farther limit. Not an ideal or responsible situation when sharing the road with tin tops. Link to comment Share on other sites More sharing options...

I have been really pleased with my Falken RT615s available in alot of sizes and are very affordable. It has won the Grassroots motorsports tire challenge the last few years. I have had them, and more expensive tires (Bridgestone RE01R and Yokohoma AD07) I still like the Falkens the best. Link to comment Share on other sites More sharing options...
pierats Posted September 18, 2007 Share Posted September 18, 2007 gjslutz, I have run my car with 13" tires on the street for 15,000+ miles. No problems. The only time I have to be really careful is with speedbumps. The 13" wheels handle better, are lighter weight, and lower your CG. I also run competition tires - not race tires. I'm currently running Yokohama A032R's. They do wear faster than a tin top tire, but they sure do grip! Link to comment Share on other sites More sharing options...
stevet Posted September 18, 2007 Share Posted September 18, 2007 Another vote for the Falken's :thumbs: Great tire for the price. Link to comment Share on other sites More sharing options...
gjslutz Posted September 18, 2007 Share Posted September 18, 2007 I had to raise my Birkin up to avoid some high center crowns in lanes from over weight trucks and dips in the road if I wanted to keep oil in the engine. Yes it came with a guard, but was getting thin fast. I would love to go to 13", but they are not practical for my driving. I live close to great areas of low traffic, low law, small hills, and many turns. I had high pointed a few times enough to make the light drift interesting. 3.5" GC was too low, with the shock & spring set-up I have & like. I would need to make too many changes to get the Falkins in a "good size" to fit under the fenders. The next 7 type will have more room. Link to comment Share on other sites More sharing options...
HPC Posted September 18, 2007 Share Posted September 18, 2007 How many people here have run DOT slicks on the road? You know, those ones with a few grooves on them to satisfy the letter of the law? Yokohama Advan A048 by standard. They are surprisingly good in the wet but one has to be careful on standing water and when it is cold (I guess I didn't have to tell that ).

gjslutz Posted September 18, 2007 Share Posted September 18, 2007 I ran the 225/50 X 15 Kumho V710's for a day, but the shower of sand & stones from the paved roads was a problem. They were like fly paper though, for handling as well as what they picked up. They are mounted on a extra set of wheels. I must have had them on when I measured the 3.5" of GC. I remeasured it today. the guard is 2.75" & the oil pan is 3.10". A dry sump would not help as the bellhousing & Tran are the same height as the oil pan. I had the car down to repack the muffler, a new one for me. Never repacked one before. Gary Link to comment Share on other sites More sharing options...
Keith Posted September 19, 2007 Share Posted September 19, 2007 I run the RA1 all the time. I have a set of Falkens, but don't like them at all. I do like the fact that I bought them for under $50 each, but the RA1s are worth the extra. Link to comment Share on other sites More sharing options...
JohnCh Posted September 19, 2007 Share Posted September 19, 2007 I ran Yokohama A032R on my Westfield until the rebuild. I’m personally not a fan of those for the street. They were really slick when cold and I had trouble getting heat into them unless it was a hot day or I had strung together a *lot* of corners at speed. The sidewalls are also really stiff, which don’t match that well with such a light car. I have driven a Caterham on Kumho V700s (now the V70A) and was impressed. Granted the weather was hot (low 90’s) but they stuck well from cold and the sidewalls didn’t seem as stiff as the Yokos. I plan to upgrade to the V70A this spring. -John Link to comment Share on other sites More sharing options...
Robert O. Urfer Posted September 19, 2007 Share Posted September 19, 2007 I have the RA1's formerly from Mazdas car and all i can say is wow. What a difference from crappy 20 year old street tires. wonderful feel and tremendous grip. i don't drive the car long distances so I am unsure how long they will hold up.

RA1 is intended to be a track tire although it is DOT approved. Falkens are a true 220 wear street tire. Link to comment Share on other sites More sharing options...
slngsht Posted September 19, 2007 Share Posted September 19, 2007 Count me in for RA1's as well... I might put 5 or 6 thousand miles a year on Frankn7, so wear is not a problem for me. I'd rather take the extra grip. Link to comment Share on other sites More sharing options...
